Some mothers of babies in the range of 3-4 months have observed that a “nap” occurs around 5-5:30pm and around 7ish the baby is up. Surprisingly, if the baby is quickly changed. fed, and briefly soothed, she goes back to sleep within 30-45 minutes. Previously, the “bedtime” was later at 8-9pm and the baby was kept up to that time. Naps improved when they made the interval of wakefulness around 7PM briefer.
My view is that the baby’s night sleep rhythm was kicking in around 5-5:30pm and the increased total net “night” sleep helped naps. Any other observations or opinions?
