Cristiana is finally sitting up on her own. She topples over still after a few minutes but she's doing it all on her own. I was a little worried when we went to our 6 month visit and she was still not tripoding very well but a little over 1 wk later and she's up all on her own. I needed to remind myself that she was 4 wks early and technically a month behind, but she's doing incredibly well and both mommy and daddy are so excited that she's developing so quickly in the past few weeks!
