Thank-you for posting this, i've been thinking about DS 12 month needles all week. He has had all the vac up to date and i don't regret that at all but he is booked in for his 12mth needles in the morning and i'm considering delaying his MMR one. i've been reading up on it and it's just what i would like to do because he is still developing, however my dilemma is DS does attend nursery at a kindy, and i'm wondering what his chances of picking up either MMR are. I asked the dr during the last visit and it was answered "i wouldn't hesitate to get it done", so i feel funny going in there tomorrow asking for one needle and having to justify my reasons for not getting the other one, when my answer is "i just don't want to get ot done yet"
