I have a five month old daughter. I've been solely breastfeeding. Sometimes she gets to where she wants to play instead of eat. My mother in law said she should be sleeping through the night by now and she's not. She didn't breastfeed and thinks a bottle would help. I'm a young mom and try not to discouraged by those type of comments but it's hard. Any suggestions for the playing, the mother in law, or getting her to sleep through the night?
