15 week old DD was sleeping brilliantly (in a normal sort of way) culminating with a wonderful week when she slept from 7pm-11pm, had a dream feed, then slept until 6.30am. She then caught a cold and it all went to pot. However she has been better for 10 days, but her sleep has got worse and worse, to the point where she is now screaming for up to 3 hours a night. She self settles at nap times and at bedtime, but will wake anytime between 2am and 4am and then cannot settle. I have tried everything: feeding her (she is not hungry and won't take any milk), offering her water (she takes a little but it doesn't help calm her), a dummy, rocking, bouncing on a yoga ball (which used to be a failsafe way to get her to sleep) cuddling, lying down with her, bringing her into bed with us. None of it calms her, she just cries and cries which is incredibly upsetting. I feel like I must be doing something obvious wrong, but I just can't work out what. She is FF, in the 95th percentile for weight, has a very regular bedtime routine (we have a 2 year old so she follows that) sleeps in a grobag in her cot, and takes approx 4 x 40 mins naps during the day. She has a dream feed at 11pm.
If anyone has any ideas why she might be so upset in the night it would be brilliant, I am finding this really upsetting and totally exhausting!
Sounds like she has started the four month sleep regression. DS barely slept at all from 16-20 weeks. I did everything I could too, fed, rocked, co-slept. it was like he was wired & couldn't switch off. It sorted itself out eventually on its own. Not much help, sorry. Sounds like you're doing all you can.
Thank you for your replies. I don't think it's teething as she's very calm and content during the day, and no real signs of it apart from the night waking. I feared it might be the 4 month regression hitting early, and I guess that's most likely. Will just have to tough it out!
