Joey is constantly trying to sit up from his laying position. I think he feels that he is missing out because he can't see everything going on. He is happiest when we sit him up to play. Well FINALLY tonight with a little support from a boppy he did it. He sat up on his own. Long enough for me to get my camera out of the case, long enough for me to lay down on the carpet & say look at me. He looked so happy, but then he tipped over & sitting time was over. We're proud of you Jojo. Now just keep practicing & soon, maybe by 5 months you will be sitting up to play on your own.
