I know it's a bit of a 'how long is a piece of string' question, but dd1 (6) has had a horrible sickness bug since yesterday afternoon, sick all rest of day and all night and feeling very nauseous today. Dd2 is 2 on Weds and hasn't shown any sign at all of this bug as yet. I had such a shocking night, very little sleep and I really don't want dd2 to get this, esp with her b'day on weds. Is there any chance she won't get it do you think? Dh and I felt vaguely nauseous last night but it came to nothing today. Dd2 hs been full of beans today and tonight.
