Anyone experience an eating regression????? Or a period of time where ur child just refuses to eat? My 7 month old the past 2 days has just refused food. Like swatting...closing lips....turning her head just won't eat. She is getting about 30oz of breastmilk a day to compensate but it just worries me. This is a little girl who was eating 3 of the large Gerber jars a day in between some bottles.

I know she has been stuffy and congested which im hoping is just it. It just worries me that she isnt eating
