Show Notes: Baby sleep or lack of
This is the first Practical Research Parenting podcast. I introduce myself then dive right into the research. In this episode I explore what is normal for baby sleep in the first year. This podcast is most relevant for parents who are expecting or have a young baby, but future topics will address older ages also. Here are the topics covered:
- Body clock: When it emerges, how it is affected, and what this means.
- Night wakings: What is normal during the first 12 months.
- Self settling: How long it takes to learn and what disrupts it.
- Interesting factoid
- Take home messages including
- Preparing yourself
- How to decrease night-wakings by improving self-settling skills
Through this podcast you will learn:
- That the body clock emerges around 10-12 weeks and what this means.
- That body clocks are “set” by light, noise, activity, food, and sleep.
- That night wakings are the norm during the first 12 months, and the ranges of normal development (see the table below).
- That babies may self-settle from some night wakings, and that this proportion tends to increase over the first 12 months, but shows a lot of variation (again, see the table below).
- That people are paralysed during REM sleep from about 6 months of age.
- Some steps you can take toreduce the number of disruptivenight-wakings.
- Prepare yourself
- 4 Steps to improve self settling abilities during the first year.
- Provide opportunities for your baby to fall asleep in his or her cot.
- When Baby cries, wait and listen for a moment first.
- Try to settle Baby in his or her cot before picking up.
- Don’t stress if none of these steps work – your baby will get many opportunities to practice.
