Princess is Rolling on Her Side

First time she turned on her side yesterday 5.26.11. She had her 4 months checkup yesterday and it went great. Two shots and 1 oral. She had a little fever last night but she's a ok. She sees things and wants to touch and hold them and put it in her little mouth. She's learning how to hold her bottle. She can sit with assistance and loves to drool! Hahaha!
