I always used a breast feed as a comforter after his jabs when my DS was very little. He had his 18 chicken pox jab last week and he only gave a quick wail for a couple of secs and then he was happy again. The thing I leant though was to take him to my Dr to have his vaccinations. My 1st experience at a vax clinic was awful - a big production line and rush rush to get all the babies jabbed. My Dr and a nurse give the jabs at the same time (1 in each leg) so there is not two lots of pain and I don't have to wait in line. Much better for him and it's all medicare so no fee either. Happy mummy, happy baby!!
