Baby 8 week vaccine

My baby girl is getting her 8 week vaccine on Wednesday

My health visitor told me it would be wise to give her paracetamol half an hour before we go

But I don't really feel comfortable doing that she is so little and I think I can always give her paracetamol if she does get a fever but maybe she won't

What do you think ?? and did you give your baby something before you went??
