Already on the go

Sigh, the cliche goes that they grow up so fast...and it's true! Here's Sebastien doing what his favorite thing is at the moment - pulling up to his feet (just by straightening his legs but still!) and standing.
Sometimes his little face goes red from the exertion of standing and he blows bubbles at the same time.
But he smiles most of the time. Now, what about rolling over?
