For my baby each time she got injection, I must keep check on her temperature, if high I will give her medicine and breast milk nor.Touch wood she is alright.
luckyQ,
my bb will feel very sleepy and a bit grumpy after shot. she got high temperature once but it wat not fever. the good thing is that you are breastfeeding your baby. if your baby is not feeling well, try to breastfeeding her more often. this will help the baby to drink more fluid while soothing his/her emotion.
