with my mothers group, when we just have one child each, if the kids had a cold, it was ok to still come to group as that was a group decision, gastro no for obvious reason, but our kids hardly got sick, but when second children started arriving the rules sort of changed as a lot more was at risk, two kids sick isnt fun, so we avoid group if the kids have a cold, plus after i had DD i had a PPH and needed blood transfusions, i was told to avoid sick people, so everyone was more wary of spreading germs!

i wouldnt go if your worried
