Bedtime 7pm wake around 7am with 3ish wakes
12 hours overnight is quite a lot tbh for a baby. Most don’t actually need that much. Average sleep needs in 24 hours are about 11-14 hours at this age so could be aiming for too much sleep. For example my son has about 2.5 hours of naps in the day and 9.5 hours overnight now. If I attempted more he would fight it as he’s not tired! X
Being ‘overtired’ is generally a bit of a myth pushed by ‘sleep consultants’ and those in the sleep training industry. If baby is wide awake after a nap they’ve likely slept as much as they’ve needed. If baby is waking more pre midnight I’d honestly say it sounds more like too much sleep overall. What time is bedtime and wake time?
