Well, I don't mean normal because all babies are different but hopefully you know what I mean!
Anyway, he's not happy on his playmat, walker, pram on my knee in fact he gets fedup of most things very quickly so it's getting impossible just to make a cup of tea sometime! I can get away with him in the sling for a bit longer but I can't cook or iron with a sling on!
It is almost like his brain is trying to get his body to do things it is not ready for.
Hopefully this is just a another stage of his growing?
