My son is 8 and a half months old,stands over 30 inches tall and weighs about 23lbs. He wears the 18-24 month sizes. When we go out I see lots of other babies who are much smaller than he is,and who are obviously older (they walk,talk,and have teeth). My daughter was a normal sized baby,even a bit small,so all this is so weird to me. Sometimes he is scared easily because people tend to treat him like he is older, they are loud and expect him to be more social than he is. I guess the worst part is I am sort of embarrassed and afraid others think he is slow(developmentally) because he is the size of a two year old,but is only 8 months. I know that's so petty of me,and it's hard for me to admit this is happening. I just don't always know how to quiet that ridiculous inner voice that worries about what other people think. Any advice? Anybody else have BIG babies??
