Children can learn to associate feeding with sleep and find that the easiest way to settle and resettle. A step you could take towards weakening this association is to move the feed earlier in the bedtime routine (for example, before the change into PJs rather than after it). You could also remove unnecessary feeds from the nap routines, if those feeds are no longer needed for sustenance.
Please add your experiences with this approach in the comments below. Please provide the age of your child when you tried it, and how long you tried it for. If it helped, please share the effects you saw. If it didn’t help, why do you think it didn’t work in your case?
