Isaac has his 8wk injections today, and I just wanted to ask if its common for babies to sleep after them? Only Isaac is quite an awake baby and I don't want to be too paranoid about him sleeping a lot afterwards if its normal We don't have a baby thermometer either, so do you think we should buy one, otherwise how will we know if he has a high temp, he sometimes feels hot these days as its warm I'm aware they can get fever or raised temperature which can be a sign somethings wrong
