So a baby aged 3-4 months should sleep between 14 and 16 hours per day. I read that low sleep babies can sleep an hour, two shorter. Mine sleeps 8-10 hours per day, that's almost half of the recommended duration. He has wake windows of 9 hours and doesn't seem tired. Is this still normal? Yesterday he slept 8,5 hours in total (so in 24 hours).
I don't think it's solely due to sleep regression since he never slept any close to recommended duration. But if this continues he'll soon sleep less than an adult..
