Nutramigen

My baby (6 weeks old) has CMPA and I started her on nutramigen. She is refusing to take the bottle. I am dream feeding her but she is taking only 2 ounces. As per her age she needs to start taking 4 to 6 ounces. I know it's not necessary that she should but how do I give her 3 to 4 ounces (her usual intake). I am just worried she will start losing weight. I already called her doctor and left a message but I need suggestions from fellow mamas!

Sincerely

A desperate mother! 😔
