How much and how long does it take your little ones to finish there bottle. My little girl has many different issues when it comes to food. She is allergic to both milk and soy she is on elecare formula. She also has horrible acid reflux and has trouble keeping the formula down. We went to a GI doctor and they now have us putting oatmeal in her formula to help keep it down because she wasn't gaining weight. So I'm wondering what are your little ones eating and at what rate!
