Dh just in from work, complaining about d&v bug doing the rounds, dmil is due to visit any minute, we havent seen her in about 3 weeks as she was on holidays, dh says dmil has it too, I said she shouldn't visit us and kids as toddler might get it, dh says ah mam is sure she got it in holidays from rich food and is fine now, and is going to call soon, aagghh, aibu not to welcome with open arms a possible d&v big into the house, should I kill dmil first if she does call with it, or dh for not telling his mother to stay away for 48 hours just in case,
