Aloha Karen, My son was a sumo. He was 7 lbs. 8 oz at birth. At 2 months, he was 14 lbs, by 6 months 22 lbs. and he continued to 25 lbs. at 1 year. People use to love to stop and grab hold of him. My ped wanted to start him on solids to slow his weight. Of course, I didn't. He slimed down once he started becoming mobile. At 5 years, he is about 40 lbs. I know many breastfed babies who grow like this. My mil insists that my husband was like this as a baby as well. Hard to believe now, he is Vietnamese, very slim. I don't know if this weight gain would have anything to do with the wheezing, but I am sure one of the doctors on the list may have an idea. Aloha, Gloria Thai Honolulu, O'ahu, Hawai'i located 20 degrees North of the Equator who will probably outweigh my husband by the end of this pregnancy
