Most kids build up an immunity to it by the time they are 3-5 yrs old (based on what his mum was told and information sheet from the doc) younger children can suffer from the bug multiple times until their body build up an immunity to it (which the serum is meant to do). But his body hasn't developed an immunity to it. So far he has had it 3 times this year.

Liz: Peg feeds are when children with special needs or swollowing disorders etc are given liquid meals through a tube in thier stomach.

Mt friend has an appointment with her sons pead to discuss if it will be benificial for him or not.

Thanks for all of your comments
