why does a baby wake every 45mins when previously slept through?

[nicg85]

How come my baby could get herself back to sleep when waking and now she wakes every 45 mins all night long?
How do I help her get back to sleep without me having to pick her up and rock her?
She's 5 months old and would sleep through until a week ago.
I end up bringing her into bed with us as she sleeps longer when I do this.

Please help me I'm so frustrated.

Is she too hot/cold? Teething? Sleep regression?

Is she waking up hungry or just needing you to settle her back off?

DD started waking up at 4am every morning at about 5mo for no apparent reason. I looked up suggestions and it turned out the house naturally got colder at that time. We adjusted the heating and she was fine.
But could be any of the reasons Wif has suggested. Babies do go through seemingly random bouts of good and bad sleep. I'd say see how she goes in another week but I know how frustrating that sounds to say.
when you say she wakes, does she self-settle at all? Would it be an option to monitor her but see how she gets on without you putting her in your bed?

Not sure. She might be too hot? She is still in a 2.5 tog sleeping bag and wears a vest and Babygrow too. Do you think that's too much?
It could be her teeth but she doesn't wake up whinging or anything.
I don't feed her at every wake up. Mostly rock her back to sleep . She does seem more hungry though.

She used to self settle when she woke but now she can't seem to sleep through a cycle. Last night she came into our bed but for the 5 nights before that I refused to let her come in and she just continued to wake hourly until the morning.

Mine is the same. Since sunday. I think it might be something to do with the clocks going forward. Room is warmer and lighter. Body clock confused. Overtired. Etc...

I'm fed up with it now.

Yes fed up too walk.

I think you're enormously lucky to have had babies that sleep through before 5 months. Both of my children were almost two before they slept through every night
Could be any number of reasons - teething, feeling a bit unwell, feeling alone and wanting mummy....
Your babies are TINY. I've always taken the approach that until they can tell me what's wrong, I will cuddle them and reassure them back to sleep. Yes you get fed up, but that's just part and parcel of having children.
Whatever you do, don't overheat a baby. Check the room temperature against the Grobag chart and dress accordingly.
I promise it will pass and you will one day miss rocking that tiny baby back to sleep!

Sleep regression maybe?

Because babies are funny buggers who change all the time. Mine has had every sleeping pattern under the sun. We just go with it now and just hope we'll have a good night (at 18 months)

I agree with just going with it too.
It gets better, promise. They all sleep eventually!

Agree with going with it and waiting to pass. But as it's happening, it is miserable. I swore at my cat today which is very out of character for me.

Nic My DS2 is 16 weeks so prime candidate for Sleep Regression. I'm trying to treat it as such by going back to the techniques that worked as a newborn. But so far they haven't been as successful as they were then. Just going back to basics and hoping for the best.

I think DS1 had unsettled episodes that lasted a couple of weeks each time. I've forgotten.
