somebody help!!! my daughter is about to be 4 months shes been sleeping through the night since 2 months. but for some reason the past two nights shes been waking up every 4 hours just about. ill make her a bottle and shell drink on it until she dozes back off. why is she waking up???
like @firstbaby_girl said they go through growth spurts so she's probably just getting hungry a lot faster! it'll pass
My son was doing that too, he quit in a couple days then started sleeping through the night again.
Teething maybe??
