God it's horrible. My ds2 (8 months) has had it with the runs for the last week and hasn't been able to keep much food down. Yesterday I had griping pains all day and started vomiting at about 6 pm. At 8 pm ds1 started vomiting every half an hour until 1am and then dp started vomiting, at 4.20am dd came into our room and started vomiting also. We are all at home now feeling very sorry for ourselves. Even though I feel very ill i've just cleaned and bleached the bathroom in the hope not to spread it anymore. What a nightmare!
