My DS is 12 weeks old and last week went from happily napping for 1.5-2 hours to never napping longer than 20-30 minutes at a time. I'm losing the will to live! If he was waking up happy then I think I could accept that but he just gets more over tired and grumpy throughout the day and it's hard to get feeds in him then because he falls asleep before he's finished.
At night he will have a bottle then go into crib awake and settle himself to sleep. He will sleep until about 4am, wake for a feed and go back down until 7 (I have experimented with starting a dream feed but seems to wake around 6 and feeding then interferes with "morning" feed).
For naps I am putting him in his crib and will generally settle himself quickly for first nap of the day but wakes after 20-30 minutes and it's downhill from there then. I've tried putting him down ~45 mins after waking up to ~1.5 hours after waking and nothing makes a difference. Is this just a phase? Can I do anything? I feel like he isn't getting much quality awake time because he's just tired and grumpy. When he is awake I'm scared of doing too much with him making him over tired but then he struggles to go back to sleep so I end up just leaving him lying in his crib and I feel bad for that as well!
Any advice on whether this too will just pass or if there is something else I should be doing?!
