Well Louis has managed to get all the way over now, and get his arms out from underneath him too . He kind of props himself up on his elbows to have a look around.
At the moment he only rolls to his right and once he's on his tummy he is stuck, but he's getting there.
I spent most of this evening wrapping the last of Theo's birthday presents and hiding them about the living room. Hopefully he'll have fun searching for them tomorrow.
