Tummy Time and big girl Reese

I put the girls down on their tummies each day for as long as they can take it (usually anywhere from 2-10 minutes).  Yesterday during tummy time Reese rolled over!  I was so excited and was able to catch the second time on video!  Tony and Jessi were here to witness it too!  I'm sure Reagan will be rolling soon but never stays down as long as Reese. While these type of milestones are exciting they are also sad because it means they are growing up and not newborns anymore!
