3 month old baby crying all night
Sometimes it can feel like when your baby is up a few times during the night, they're crying all night. But, if your baby at any age is literally crying all night long, it's time to see a doctor. When you've exhausted your list - are they dry, are they hungry, are they gassy, too hot or cold - and they are still crying, then it could be something you can't see. Reflux, for example.
