Sorry to come across as a bit thick, but is the Pre-School booster purely an MMR Booster or does it also involve something else? Tried looking through the archives but still a bit confirmed.
Just got an appointment through from the HV for dds Pre-School Booster but am confused as she has never had the original MMR.
I don't want to cancel the appointment if it means her missing something vital and also don't want to have to ring the HV for advice if I can help it as I have recently made a complaint about them!
