My bub is 12 weeks old. During the day I watch him closely and swaddle and put him in his cot when I see a tired sign. Most of the time he grizzles for 15 to 40 mins then closes his eyes. BUT... he opens his eyes after a few seconds and seems to not able to go to sleep although he wants to. At this point I normally put him on his side (if I haven't already), put a hand firmly on his arm and sometimes pat his back if he still grizzles. He normally wakes up in just 1 sleep cycle of 40 mins and 80% of the time can't resettle unless I help him immediately (firm hand on arm, patting, breastfeeding, etc...).
At night time he sleeps on his back and normally has no problem going to sleep by himself. But he always wakes up every 2 hours (since birth) and if I don't feed him he will cry. But I suspect it's more comfort sucking than hunger because no matter how long I feed him - 1 min or 20 mins, he will wake up 2 hours after that.
Is it true that he can't resettle because he doesn't self settle to sleep in the beginning? It's confusing for me because I think he goes to sleep by himself but somehow can't manage to resettle.
