DD is 16 weeks and up until the last few days has slept ok. The last couple of weeks she'd been going to bed about 8, fed at 10 (I woke her for this) then woke once about 3 or 4 for a feed then straight back to sleep until 8ish. It has all gone pear shaped...
Now waking twice most nights. The wake-up after 3am involves her being wide awake, waving arms, gurgling, smiling and generally being Playful. She's awake for 2-3 hours and it's killing me off! By the time she's going back to sleep, DS is starting to wake, so I'm basically starting the day at 3am. If I leave her for a bit she just talks to herself then starts to cry because she wants someone to play with, and wakes up the whole house. I'm always really careful, don't make eye contact, keep light dimmed etc, but it's not helping.
I'm BF. Not sure if this is relevant or not. I BF DS but didn't get this problem. Any suggestions very welcome.
