My son is on the small side for his age; he's getting taller now, but for a while there he was really tiny. He's also been slightly advanced in terms of physical milestones and very advanced with intellectual, social, and emotional things for his entire life. He's 28 months old, looks and acts about 40 months old and is the size of the average 20 month old. For a long time, people would assume that he was a premie and ask me how early he was born, because he looked and acted so much older but was physically smaller than other kids. I don't get that so much anymore, but I do get strange looks from people when I say that he's two. He's the same size as a lot of smallish two year olds, but he really acts a lot older, and looks much older (especially since his haircut!

) than that.
The premie question got old very quickly, and I always felt defensive and miserable when people brought it up. I was really glad when he started to grow a bit after BooBah was born. Now people assume that he's older, despite his small stature; I guess they're finally realizing that I myself am not all that tall (people seem to forget this, even in real life

) so it's perfectly reasonable to expect that my son wouldn't be huge.
Miss BooBah is 25th percentile for her age, so size-wise she doesn't come across as exceptional. She's *very* advanced developmentally, though, and I get really strange looks from people when she talks to them, or climbs up stairs, or claps in time. She's very sweet, but not as extroverted as her brother and it seems to me that people are already put off by her on some level. I've seen parents with slightly older babies just get up and leave the park when they see BooBah climbing the stairs to go down the slide, and that really makes me feel bad. If that sort of thing can happen now when she's really just a baby, what will it be like when she's older?

Then there's the fact that I always feel a bit defensive when someone mentions that my babies are small. It's totally irrational, but I feel insecure when I see a baby who looks all big and round, the way that babies are "supposed to look." I guess I've got my own issues.
At any rate, I've got a niece who's going to be 5 years old in a few months, and until she got sick a month ago weighed 65 pounds and was just shy of four feet tall. She's got Asperger's Syndrome, so despite the fact that her development is nothing short of remarkable for the autistic spectrum, people assume that she's older because of her size alone and that she's very far behind. People often expect much much more from her than is reasonable, things that they wouldn't expect of any normal-sized four year old to say nothing of a four year old with Asperger's. It's very sad, and irritating to deal with. On the up side, she looks and acts like a 3.5 year old, just a huge one, so it's not difficult to get people to believe that she is her actual age.
