Well really 4 and half month check up. She weighs 14 pounds and 12 ounces (75%) and is 25 inches long (55%). I have been giving her 1 bottle a day of formula at 6:00 to give myself a break and to fill her up before bed. The Emfamil made her spit up and the Good Start Soy made her constipated. Dr Montague gave me a sample of the Similac Alimentum and she wants nothing to do with it. So trial and error until we find one that works. I plan on breast feeding until she is 6 months old.
