Hun, I had a tummy bug 5 times when pg with DS2. It was the absolute pits, especially with a toddler to look after as well, but the baby was (and is!) just fine. No need to worry about that. Just do what you can to not get dehydrated, and if you do, let your carer know as they can arrange for you to go to hossy for a drip. I hope you feel better soon.
