My son had his 16 week jabs today. At first he cried a bit but then he was smiling within a few minutes. He seemed more tired than usual but apart from that he was fine until I gave him his bottle for bed, he ended up being sick everywhere (and not just the usual bringing up milk) I gave him to my partner and he told me he seemed hot so he stripped him to his nappy and checked his temperature and it was 38.1. He's seems very grumpy and we're struggling to get him to settle. We had given him some calpol before he was sick but I'm not sure he had any or if he threw it all up. Is this normal? I don't think he was like this with his other jabs
