Has anyone ever used a numbing cream or vapocoolant for infants 2 month round of shots

So my daughter is getting her first round of shots not counting the hepB 1st dose she got when she was born in 2 days. I was wondering if anyone has ever given their infant around 8 weeks old a numbing cream or vapocoolant when they got their shots so it would lessen the pain for their baby. I read on CDCs website and they taking about numbing creams and or vapocoolants can be used to lessen the pain of immunization shots. Also I read some Canadian pamphlets or something that also talks about numbing creams etc. before having your child get a shot. I honestly don’t want to have my child be traumatize or scared of going to the doctor office or have them connect doctors office with shots or pain. So I was wondering if anyone ever tried it. And what were the results and what was used and how much.
