Thanks Keira and Rachael!!!

Just had his mchn check up - she doesn't really have any solutions...she recommended a day stay but I really don't think thats going to help...
He's gained heaps of weight though - 742g in a f/n - he's now 4.6kg! OMG!

I'm going to try some of the over the counter stuff - infacol etc and if that doesn't work the osteopath sounds like something to try!
