Luke has been able to roll from front to back for quite awhile now, but has never rolled from back to belly. I wasn't that worried about it because he does so many other things well (sitting up, etc) but at his 6 month appt our pediatrician commented that after 7 months if he still hadn't rolled then we might want to think about calling First Steps to get an evaluation. We weren't really going to because he's seemed pretty close, just not interested, but it is with great relief and pride that I can say at 6 months, 3 weeks, and 2 days - he rolled!
And following in his daddy's footsteps - he apparently is going to be a car guy. It was the car toys that Aunt Karen bought that actually got him to roll.
Here are times #2 and #3 this evening. (He cheated in #2 and used the mat to help pull himself - hey, whatever works I guess.) Go Luke!
