DS is 17 months. He got his first cold at 11 months. It turned into a sinus infection. At nearly 13 months he got another cold and that turned into an ear infection. 15.5 months he got a very nasty cold and again turned into an ear infection. Now he is his 17 months and another cold! All of his colds/ear infections except the one at 11 months he got a molar or canine tooth at the same time. At 15 months I joined the YMCA and have him and his sister (36 months) in the child watch area for 1 hour 2 times a week. DS is still breastfeeding, has never recieved formula and never been to daycare. What the heck! I can't imagine how sick or how often he'd be sick if he were not breastfed. My daughter was never sick until 14 months. In three years she's had maybe 3 colds! What is wrong??? I feel like my milk this time around is not as protective as it was for my daughter. My kids are 19.5 months apart in age.
