My 13 month old daughter is due to start at nursery in 2 weeks' time. I am wondering whether I should arrange for her to have the MMR jab prior to this and have provisionally booked it in for tomorrow. It's such a difficult decision to make, but I worry that were I to leave it until she is 18 months old, then there is a risk of her catching the likes of measles, especially now that she is going to be in daycare. We live in London and my doctor has told me that there is a slightly higher chance of measles etc "doing the rounds" than elsewhere in the country. What do other people think?
