Pre-school booster - how many jabs?

[DieselBlue89]

My son is having his pre-school booster this week (he's 3.5). I have "magic" analgesic cream left over from a blood test so my plan is to put this on a few hours before so it's less painful. But... I'm not sure where the jabs are or how many! To those whose kids have had them - can you remember how many jabs and where they were (arms or legs). Dreading it now he's old enough to understand what's going on Thanks for your help!

My DS had his back in about Oct/Nov time, and it was one in each arm. I think it's far easier when they can understand and be bribed!

DS cried a little but was easily distracted by the nurse giving him a sticker! I took chocolate buttons and he had a couple in the waiting room and the rest after. It was over very quickly.

@PeacefulInTheDeep Thanks! Chocolate buttons are a good shout!
