All three of my kids have got this again, they contracted it last term and I had to keep them off school for ages. DS and DD2 are fine with it, a sore mouth and itchy feet and hands but DD1 has a temperture, is shakey, and quite ill. She is quiet and certainly not herself. I can't workout why a simple illness can knock a child about so much. If she gets a cold she is laid up for ages. She is only 4 so I know she not faking it. She has CP and I wonder if her immune system is poor and whether I should get it checked.
When she was 4 months old, DS got croup, she got Bonalitis (sp??) which is the same virus (I was told by the hospital) and ended up in hospital on o2 for a week.
