Now, the answers to that question are many but I have one specific answer. One night Travis and I were watching a little TV and Ayda comes out from her toy corner and her pj's were stuffed with balls...yes balls. Tennis balls, ping pong balls, little footballs and baseballs. She had unzipped her jammies and placed her bouncy balls in and zipped up. It was hilarious, every step she took you could hear rattling from some of the little toy balls. When I unzipped her pj's not only did I find all those balls but I found puzzle pieces too. That's right she had about the whole alphabet, fish and all kinds of wild animal puzzle pieces stuffed in her jammies. She is crazy!
