Waking up every 2-3 hours

Amanda

My baby is 6.5 months. She is waking up every 2-3 hours at night. I feed her and she goes right back to sleep. But this often is getting exhausting. I thought she was teething but I could be wrong. Then I thought maybe she's just thirsty so I give her a little water before I feed her. I dont know what is going on.
