Bryce was the first to sit up on his own. Sunday(1-3-10) Bryce sat for 30+ seconds balancing himself. Collin and Addison sat up too but they were not as stable as Bryce was. Bryce also rolled over from his back to his tummy for the first time last Tuesday (12-29-09). He only rolled over once so I wanted to wait for him to do it again before I officially said he did it but he got sick Wednesday so he didn't feel like laying on the floor and rolling around. When he rolled over he started to cry and we aren't sure if he didn't like being on his tummy or if I scared him from screaming with excitement! Now that he is feeling better we hope he will get used to being on his tummy and roll over more.
