My baby wakes up at the same time every night. She is 8.5 months old and goes down around 7pm and previously that would be her until about 3/4 am. Now she will wake up at the same time every night around 1:30am then again at 5:30 am. She has 3 meals a day and snacks, plus milk in between and 7oz before bed. She’ll drink 6oz each time she wakes up. Any advice on what to do?
