We had a few concerns that our AS3 was small for his age (0.4 percentile). Our GP referred him to a paediatrician and when she saw him she has suggested doing some genetics tests. I'm assuming she thinks he may have some sort of genetic disease/syndrome to do this on the first visit? I have suspicions as to which one but surely this should have been picked up on by the placing authority? Blood tests were taken so now it's the waiting game. Anyone else been through this?
