DS1 is 13 weeks old and from day 1 has been a great sleeper. Went down at about 9:30pm, woke around 3am for a feed, back to bed and then awake again at 6:30am. At around 2 months he dropped the night feed and was waking at around 5:30am, which then became his first feed of the day. I managed to stretch this out until 7am. All great.
For about the last 2 weeks he has been very disturbed throughout the night. He makes crying noises (but not full on crying) every 1-2 hours. I put his dummy in, put Ewan the sheep on and he resettles, but he'll be awake again in an hour or so, sometimes even only 2o minutes later! That goes on throughout the night, so I never get more than 2 hours at a time.
He's primarily formula fed with as much expressed breast milk as I can managed throughout the day. Always formula before bed and we make sure he has something before he goes down.
I wondered whether it's the 4 month sleep regression come early? Anyone got any ideas?!?!
