Thanks Caro - good to know there are other children out there like it - I knew there had to be but sometimes you can feel like everyone elses children eat so well.
Yes he does sometimes refuse the yoghurt - maybe he gets sick of having the same foods - I don't know.
I hear you with the weetbix tho - if I try to feed him normal weetbix instead of the bite-size ones he will not eat them unless they have margerine on them. And he prefers the little ones with a splash of milk and then I have to tip the milk off.
I will give the Pentavite a go - hopefully it might work although other vitamin tablets I have tried on advice from the chemist he has refused to eat and one brand he vomited back up. It would be good to not have to buy the formula, it is pretty expensive.
Thanks for sharing your experience.
