Why is my baby not sleeping through anymore?

[tigerbreadandtea]

About three weeks ago my baby started sleeping through the night, going down at 8pm and sleeping until 6.30-7am.
This past week she has woken every single night between 3-4am and drained a bottle. She has four 7oz bottles in the day and some food, she's just turned seven months so weaning is still more about exploring at this point rather than her eating loads.

Because babies/toddlers sleep can change a lot. DD is 2.5 and has done everything this year from waking every hour to sleeping through, I've not changed that much, 9/10 months was a really bad patch for sleep for us.

This is a good article on baby sleep and what's normal, her sleep book is good too drawing from solid studies and research.

Sleep isn't linear! There are lots of developmental changes happening which affect sleep, could also be heat, teething, a growth spurt, just generally needing some attention. Adults don't often sleep the whole night without waking so why should a baby?

If she's about 29/30 weeks then it might be that she's just realised you can leave. So will be unsettled. It's just a development point and hopefully she'll revert back soon.

Have you seen the wonder weeks app. I found it really useful with all three of mine. It lets you know when babies have developmental leaps. Some go by unnoticed others are bigger and lead to unsettled, upset behaviour. It can't stop the behaviour but it gives you a bit of a heads up it's coming.

This. My DS (now 7) followed all the leaps and stormy moments to the day. It was incredible.

I don't mean to be rude, but did you really think you had cracked it and your baby would continue to sleep through from then on? Mine is almost 2 and I don't think has gone more than a fortnight of a consistent sleep pattern despite strong routine.

She's always been a good sleeper at night and has consistently increased how long she sleeps at night. We didn't even experience the four month regression that everyone talks about babies waking up every hour etc. I've just checked the wonder weeks app and it is that red phase where they realise you can leave them apparently, so it does make a lot of sense. Fingers crossed she'll settle down again.

Sounds exactly like my youngest he was an amazing sleeper until 6 months and low and behold a tooth emerged! He didn't sleep well again until a year old! He cosleept and was breastfed so at least I didn't have to properly wake up every time he did! By a year he was sleeping through the night and in his own bed.

I appreciate you say food is about exploration at this point, but when we went through similar phases we did up here calories during the day and it often helped. Just adding baby rice to her purées etc. If she’s draining a bottle she perhaps needs something more to see her through?

Because babies are assholes.

Err. I mean. What they said. These things change a lot. It'll calm down. Etc.

Can you tell mine is teething?

@ElectricMistofelees mostly in the day she doesn't drain her bottles it's just the one she has in the middle of the night, I guess it is because it's been 7-8 hours since the last. She is slowly showing more interest in food. Most of it seems to end up anywhere but her mouth.

This is so painfully accurate! DP tried to book something around DDs sleep pattern to help me out and her sleep has changed by two hours despite us not changing anything

See I guess I've been lucky because she has been a consistently good sleeper and haven't experienced any regression before!
