DD is 3 yrs old and started at a Montessori preschool in Sept. I love the M model and thought the idea of her being in a classroom with 3,4,5 and 6 yr olds was great.
But the only side of the mixed ages that I get to see is when she comes home every day with new things she's learned from them. Some days it is just an attitude, I can't think of a way to describe it but she's just kind of got attitude. Other days she comes home with phrases like "Batman poopy" and yells them over and over and over again all day long. (She'd never even heard of batman before this, and certainly never used the word "poopy").
Now, I don't mean to sound all prim about it. I do know that this kind of stuff is inevitable. But I really don't think DD would be doing this stuff for at least another year if she wasn't in Montessori. I feel like she's losing her innocence of young childhood too fast.
Please remind me why it is good for her to be in a class with older kids. Obviously I can understand on an intellectual level that she must learn good stuff from them too. I just seem to lose sight of that when see what she comes home with.
