Thanks ladies.

DS isn't verbal enough to be able to tell us if something is hurting him, I wish he was! And we haven't been around anyone who limps, that I can remember.

He's still limping a little today so have made a gp appointment, can't get in until Wednesday though... He doesn't seem to be in any pain and I still can't see any obvious cause, will just have to see what the GP says.

thanks again
