Adam, 6 months and sitting up.

 I put this basket of toys in front of it and he tips it towards him to grab a toy out.  He plays with it for a while and then drops it.  When all of the toys are out of the basket and on the floor I gather them back up and put them back in the basket so he can do it all over again. 

I love these two together.  Lachlan is so in love with this little guy.
