My 11 wk old has had issues with eating since about 4 wks old. She fights eating. She will take most of her bottle but she wiggles, squirms spits it out then sucks back in. She is already being treated for reflux. She doesn't spit up much. Now we're switching formulas to see if that helps. She has been on Similac pro advance and pro total comfort.

Interested to see what everyone is using and anyone had experienced this.
