Isn't he growing up? Almost 5 months now and extra cute. When he was visiting at the weekend I dug out this old Fisher Price 'Happy Apple' musical toy that I got as a baby shower gift before my daughter was born almost 35 years ago, and he loved it. It's a "staying at Grandma's house" toy though. I see these apples are very collectible now, selling on Ebay for quite a lot.
