I have 4 kids, 8, 6, 6, and 2. My son, who will be 3 in October, has always been in the middle of everything, just like the twins were for their older sister. It's been messy, but it makes participating in learning a part of their lives, rather than something we shut them out of until they're "old enough."
I am a huge believer in learning being a natural part of life, rather than trying to squeeze life in around the edges of a schedule. So, even though it means stopping for a minute when the baby dumps the cuisenaire rods, I am glad to have it this way. <img src="/images/graemlins/laugh.gif" alt="" />
