I am a big fan of the book "Brain Rules" by John Medina, so am delighted that he has written the "baby" version!

I am so enjoying Markus learn new things, each day he figures out something new. We are currently learning how to descend bum first from the sofa. He know waves to us first, without prompting- Very cute. However, he hasn't yet learn that our bed has an edge to it. He has yet to fall out of the bed, but I think it will be soon..
