And over again

Last night I laid Justin on the floor on his belly as the boys wanted me to look at something in their room. When I got out of their room, Justin had rolled onto his back. Then we went into the kitchen to do something and when I checked on Justin again, he was back onto his stomach. He rolled back over! I seen him trying to do it later that evening, but then his brothers sat down to encourage him so he stopped trying. I told the boys to move and leave Justin alone so that he would try to roll over, but that was impossible for them to do.

I was suspicious as to if Justin really rolled over on his own and asked the boys if they "helped" him. I didn't see them leave the room, but that doesn't mean they didn't. Both boys said that they did not help Justin rollover. I believe them because before they got into Justin's face, he was trying to roll from his back to his belly and he got close several times. He is 16 weeks old and already becoming a little man! Where did my baby go?
