Throwing her milk back up

Chantel

My little girl is between 7/8 months and over the past couple of weeks she's been randomly throwing all of the bottle back up I can't be over feeding her because she will only eat what she wants as solids breakfast dinner and tea and has a little milk in between that... I always offer her milk first as it's more important than her solids but it's not all the time she is throwing her milk back up unless she drinks more than 4ounches then it all will come back up 🙈
