DD is 10 weeks tomorrow. She has been bottle fed for 4 weeks. She is now up to 6oz a bottle but wants feeding every hour/hour and a half! She's on 9/10 bottles a day! I'm worried she isn't getting enough and she is feeding pretty much constantly (I was advised to put her on formula in the first place because she was literally on the boob all day every day and wasn't gaining weight). Has anyone successfully moved on to hungry baby formula?
