Preschool booster and MMR singles for a 3yr old..Advice please

[shhhh]

DD is due these in Nov so im trying to do groundwork now...

She has had all vaccinations at the gp's apart from the MMR which was done privatly in single doses.
Im not to hot on the background as dh did all the research yet we both agreed iykwim...but think mostly due to loading immune system..

Now dd is 3 (will will 3.6 come the time..) are we advised to do singles again or opt for the 3in1..? Just because she is older and a bit stronger iykwim...or should we do singles again..?

At the pre school vaccinations is it boosters of dip, men c and the MMR in one sitting..?

Slightly confussed .

Advice appreciate. TIA

My daughter is having the MMR booster on wednesday. I hate her having injections, it's so awfull to see her in pain. I'd go for the 3 in 1 so she won't have as many injections.

Was also wondering about this for my DS1 who is 3.
Not sure where to look for info this time round, hope someone can offer some advice...

The pre-school boosters consist of diphtheria, tetanus, pertussis (whooping cough) and polio, all in one injection, in one arm.

The other arm is usually the MMR if you want it.

I am pro-MMR but appreciate it is a very personal decision to make.

Didn't realise till now I have posted this x2...

Got advice there also...thanks for replies here .

Other thread also suggested having a blod test done to see if immune system is covered iykwim. Apparently in most cases a booster is not needed esp when singles done.
Just for those of you who are in same situation as us..

Thanks again x
