DS7 was diagnosed with mild autism at 21 months and had all his vaccines up to date now I wish I had delay them as he was 4 weeks prem but can't go back and change it. DD came along 19 months ago and we have delayed them competely. She had the 6 week one at 5 months and the 3 month one at 11 or 12 months. She has not had anymore since as we are still in two minds about the whole thing. At the last one she came somewhat less reposnsive and just wasn't her bubbly self and hardly use any of her words for about a couple of weeks.
