sleep

Nope don’t think you should overtired a baby, it will shorten their attention span if they gets overtired and cranky. My LO takes 3-4 naps about 30mins each in the day (my LO hardly sleep past 45mins, he is a very light sleeper during the day). Even if his bedtime is at 9pm, I still let him have his last nap from 6:30pm-7pm as I will only let him be awake for 2hrs to 3hrs max. He has been sleeping well since 2MO for at least 7-8hrs (sometimes 10hrs) straight during the night.

Depending on the age of your baby, babies generally need 2-3 naps during the day so that they won’t be over tired and be cranky during bed time. For example, awake time should be about 2-3 hours max for a 4-5 month old baby and a 1 hour nap. So if a baby doesn't have enough awake time during the day, it can lead to multiple waking overnight, unsettled behaviour in the early evening and/or early morning waking.
