My baby (4mo) has diarrhea after her rota virus injection, is it normal ? When should I go and see the doctor ? She is not cranky or restless but just act as per normal except that she poo often and its watery. TIA

Yes, it can be for some children. My PD told me about it as the injection is to help build up the children's immune system. For some, it can come with mild fever. If rashes appear, quickly consult a PD. Otherwise, I think ur bb should be ok.
