At 19 weeks, Gretchen is rolling over! She's gone from back to belly many times after weeks of rolling to one side. The other day she even rolled from belly to back! This little girls doesn't like to be in the bouncy chair (reclined one) anymore, she is always trying to wriggle herself out of it. The jumperoo is another story though. She loves the lights and can spin around in it. I can't remember when Charlotte first rolled over, but this it seems Gretchen is doing things right!
