DS2 is nearly 6 months old. Only takes 30 min catnaps and wakes two hourly or more overnight. He will nap for longer if held but if I put him in his crib with curtains shut and white noise on he will only sleep 30 mins on the dot. Over the last few days he has started to fall asleep on his own in his crib with his dummy which is great because I’d previously have to rock or bounce him to sleep for every nap but despite being able to “self settle” now he still only sleeps for one sleep cycle. Will he grow out of it? When did your baby stop catnapping? He wakes up grouchy and tired and I feel like he needs longer but won’t have it.
