Miss Olivia is now 5 1/2 months old! She is 17 lbs! She put her toes in her mouth for the first time this week. She is rolling over all the time now and loves to sleep on her belly, esp on mommy and daddy's bed! We got a new convertible car seat this week and will be installing it tonight. It is a big girl seat because it can hold up to 65 lbs and can sit rear or front facing. Olivia is almost sitting up on her own. Daddy lowered her mattress so that she can't fall out when she is pulling herself up on the sides of the crib. More to come...
