When I had my last ultrasound DH commented to the sonographer that there seemed to be a lot of open space where the brain should be. She laughed and said yes there was, the brain gradually grows to fill in the space.

She said she often gets parents wondering if the baby gets bored in there and she has to say no...there's really not a lot going on upstairs, the babies are kind of like goldfish at this point!! Even when they are born they aren't really capable of complex thoughts, the brain is still developing.

So what do they think....? Not much, apparently!
