whoa!!

this morning i gave olivia her morning bottle about 9 and then laid her down on the playmat thingy for some tummy time. i use this time to straighten the house, dishes, etc... i came back in the living room and she had ROLLED OVER. now, i by no means know much about being a parent but from what i do know they aren't suppose to do this until at least 3 months. is that correct? now my plans for the day have changed; i'm now planning to sit here all day attempting to capture this on our video camera!
