Wow, my DS is 12 months and just a hair over 17 lbs. Our ped was not concerned at first since my hubby and I are small. But when he dipped below 5%ile, she wanted the GI specialist to chime in. By the way, my son is allergic to dairy and soy. I think he's fine, all milestones are met, etc. However, my mom says he needs a little "reserve" in case he gets sick. I can understand that with flu season coming up. So, any ideas what to give a kid for snack that will really pack on the pounds?
