Feed your baby to sleep – The possums sleep intervention new recommendations

Feed your baby to sleep (Image)Don’t feed or rock your baby to sleep is common advice. A new take on the same theory suggests that this advice is flawed. As detailed here, the dominant theory is that feeding or rocking can become associated with sleep. The concern is that the parent is then required for the baby to resettle after every sleep cycle. This assertion is not necessarily warranted.

To listen to a combination of the current post and this post (also on sleep associations) please check out my Sleep Associations Podcast Episode.

For an interview with Koa Whittingham, a co-author on the Possums Sleep Intervention, see The Possums Sleep Intervention Podcasts.

A new approach, called the Possums sleep intervention, suggests that the association between feeding, body contact, and sleep is biological, not learned. Rather than trying to break this very natural association, attempts should be made to retain the association between sleepiness and sleep. This is a very good point. When babies get sleepy while feeding or rocking, ripping them away in an attempt to lay them down “calm but awake” may build an association between sleepiness and sudden disruption and parental disappearance, and break the association with sleep. The possum sleep intervention authors argue that a disconnect between sleepiness and sleep underlies some adult insomnia, and may be problematic for infants.

The possum sleep intervention requires scientific testing, but fits with the research on a theoretical level. Recommendations for the first 6 months are as follows:

  • Learn to interpret and respond as best you can to your babies cues.
    • Don’t delay your response, or respond with something other than what your baby requests unless necessary.
  • Encourage consolidated night sleep by setting the body clock.
    • Provide sun exposure in the morning.
    • Provide natural light and noise levels for all sleeps, such that daytime sleeps are light and night time sleeps are dark and quiet.
    • Bring your baby along for pleasant, rewarding parental activities during the day to ensure sensory stimulation.
  • Excessively frequent feeds may indicate a feeding issue – see a lactation consultant.

The possum sleep intervention does not aim to maximise the number of hours infants sleep at night but rather improve the quality of infant and parental sleep. This is a valid goal, but from a scientific perspective it may be hard to measure, and wouldn’t allow comparison with the sleep interventions already tested. The only testing of the approach to date did not include a control group. Therefore, the reductions in crying and improvements in the mother’s mood observed could just be due to maturation of the baby. I will post updates in the comments as they are released.

So where does this leave us in practice? Let’s assume that the possum sleep intervention receives some support. I believe it doesn’t have to contradict the advice of laying your baby down sleepy but awake, only moderates it. In the first 6 months, when your baby is sleepy, help him or her to sleep. If all the help required is placing him or her in a cot – great! Sometimes (or often), this will not work, in which case don’t beat yourself up about doing what comes naturally, whether that is feeding, rocking, or patting. As most experienced mothers will tell you, the same method doesn’t always work. Don’t limit your toolbox to cot-bound settling. This way you can retain the sleepy-sleep association and help your baby to experience a variety of sleeping conditions.

Have you fed your baby to sleep? How did that work out for you? Please share your experiences by adding a comment. Also, I have collated all my research on sleep. For a summary of what I have found see the sleep category page.

  3. I have a 7-month old currently, and I feed him to sleep most of the time. It seems easier to me than rocking/soothing him to sleep because he always seems to resist that. After I have nursed him to sleep for the night, he usually wakes up two hours later — sometimes he is resettled simply by me patting him and sometimes requires another short nursing session to resettle. I love that feeding to sleep is so easy and cozy for both of us, but I suppose it puts a little more pressure on the mother since she is the only one of the couple who can do it (unless maybe you can bottle-feed to sleep?).

    • Hi Jennifer, I completely agree. Feeding to sleep is very pleasant and easy. A lot of people recommend against it because it can become a habit. It can mean that baby wakes up soon after, when they realise they are no longer in that happy feeding place as you found, and yes, it is more responsibility on the Mum. When one or all of these points become a problem, then you can work on building new associations, but in the meantime, I see no issue with enjoying the very natural, biological sleep association. Has anyone found bottle-feeding (expressed milk or formula) can have the same sleep-inducing effect? I have never tried. My suspicion is that milk expressed at night would be most sleep inducing, because it has the sleepy-making neucleotides (technical term). Nicky

  12. I’m currently trying this method for over a week now, and so far I have to say it has its benefits for now. 80 percent of the time that I breastfeed her with the intention of having her nap, she naps. Then I simply withdraw my boob and pat her back for a minute while I walk to the crib and lay her down still mostly asleep, and she will sleep for half an hour, very rarely an hour. If she wakes up crying, I pick her up and attempt to burp her for a minute, offer her some more boob to see if she was still hungry. At times she will drink some more and then be bright eyed and awake, other times she will nap for another half hour or so. If she doesn’t wake up crying then I assume she had enough sleep. It’s great in that I don’t have to endure her screams when rocking her to sleep for sometimes more than the time she eventually napped for! And not having to watch the clock and calculate and stress over it. It’s liberating! And even though she gets a little less nap time overall than when I was stressing it and forcing her(2 hrs a day vs 3 or 4 hrs) I feel a lot less stressed during the day, and as far as I can tell, her night sleep hasn’t changed much if at all. She still wakes 2 or 3 times to feed and goes right back to sleep. So-win win! My only concern is. … What about when it’s time to wean her? No more boob crutch! I worry about that. ..

    • I also found this sort of approach very liberating, and I’m glad you have too. It is true that the one constant is change, and what is working now won’t always work, but you’ll find that you will develop other strategies that work just as well, and fit with your child’s age as she grows. There will also be times when the current solution is no longer working for you or her for whatever reason. That’s pushes you into the next change until you find the next thing that works.

      Something I learned from Koa is the importance of staying in the present. I get wound up when I’m thinking “if she doesn’t sleep now, she’ll be tired tomorrow, then we’ll have a horrible day…” that makes me tense and snappy, which makes everything worse. The thought that makes me tense is a whole lot of future concerns that may never eventuate. I’m much better off just focusing in the present (but I know from experience that is easier said than done).

      All the best, and enjoy the moment especially while it is working, but even when it isn’t.


    • I can totally sympathise with this! after several people (and a rubbish book) ‘advisimg me’ that she ‘should be’ napping in her own cot for 2 hours, I tried to implement a more structured way to get my 8 month old to sleep in her cot for daytime naps, but ended up spending twice as long both stressed out than the length of her actual nap! (She also only sleeps for 30-40 minutes at a time then wide awake and smiling!) Both much happier cuddling up and feeding to sleep when it seems the right time for baby, not on schedule.

  13. Hi there, I made the mistake of attempting the whole drowsy but awake thing and it made bedtime a fight and my baby really fights sleep now. I am hoping this can be undone as I feel badly about the whole thing and want to restore her good relationship with sleep. Thanks for any thoughts you may have!

    • Hi Nikki, we all make mistakes (I know I have made plenty). Babies and children also go through phases where they fight sleep, so you can’t know for sure whether it was your doing. It is really frustrating when children fight sleep. I’d start by making sure that when you are trying to get your child to sleep, she is biologically ready for sleep. You can use my free sleep mapping email series to figure that out. If getting your baby to sleep is not working for you (too long/ too involved), I’d look at ways to make that process more enjoyable/relaxing for you, or try gentle methods of changing the routine such as the “sensible sleep solution“. I hope this helps. Sorry I didn’t respond sooner.
