I think there’s a bias when we’re looking back at our own experiences and memories because we see how simple they were compared to our older selves. I know before I had a kid I had a very dim view of their mental capabilities before age 4, and thought people were bragging and exaggerating what they could do at that age. However, now I’ve got my own who says things almost every day that surprise me, and I’m so impressed with what he can accomplish. I don’t think we give them enough credit, or enough chances to really show us what they are capable of.
