If your LO is in preschool, do you still work on things with them at home? Like letters, numbers, colors etc...
I was really good about working with LO the summer leading up to the school year, and she really enjoyed it! Now that she is in school I've slacked on working with her. I guess I figure I'm paying for someone else to teach her these things so we spend the other time just playing/reading and doing other things. I'm sure she is still constantly learning things from me, through play, though.
