DS plays with all of DD's old toys but is bored by most of the baby ones. I remember that DD really didn't ever play with most of the toys we got when she turned one. He just chews everything at the moment but loves playing with the plastic garage.
Maybe some wooden toys.
Feel like a balloon and some wrapping paper would keep him amused on the day!
Any suggestions really at a loss. DD will get a big pile of toys don't really want her to see DS getting practically nothing.
