i know this is ticky and perhaps i'm feeling sensitive for lack of sleep and stress. . .
but i think it is safe to say that boys and girls develop differently. i notice that my young son has more physical capacity and coordination than girls his age, but the girls have more capacity for communication and also quiet activities like reading and the like. This is, of course, in general.
This is partly why i don't believe in developmental "milestones" so much as observing the process and determining whether or not more help is required for certain children. My son is actually "ahead" on the majority of his milestones and understands language very well, but actually uses very little spoken language (he does use words and short sentences, which is ahead of "schedule"--but it's rare rather than his norm).
I prefer to say that they are developing in different ways, as i'm sure the little boy who is two years "behind" in communication is more developed in other areas where a little girl of the same age may not be.
just being ticky, and i'm not taking anything personally. I'm just feeling a bit of. . . .hhmm. i don't know. and it's not from you. i totally own that it's in me right now.
i think that i feel that little boys are often disparaged in our culture in general because they do not easily fit into the cultural models for children, which is so based in discipline/punish, schooling models (being quiet, sitting, etc), and so their own developmental needs and methods are completely overlooked or seen as problems.
my aunt works with a lot of parents of little boys who have been labeled "problem children" even though they are just being "normal for boys." they tend to need a more "3-D" world experience than little girls until about age 9 or 10 (my aunt observes), and then little girls tend to go more "3-D" as they head toward 9 or 10.
Anyway, yeah, that's just me. I wanted to say it because i have a little boy who is very active, and sometimes people comment on it in a disparaging way, even though he is great great great at indoor voice, communicating non-verbally, and is great and polite in public. he is also very gentle with other beings (humans, animals, plants), even though he is so active.
just a two cents.
