I have a genuine question and one I feel a bit stupid asking. I have 8 month old twins so when we catch a cold we are sick for ages... usually one baby, then me, then the other baby. I assumed that if one of us had a cold we shouldn't be going to any groups or activities so we end up being quarantined at home for two or three week stints. But yesterday at the library reading and rhymes session I noticed other babies with coughs and obviously snotty noses so wondered if my assumption was wrong. Obviously if the children were very ill I would keep them home but if they are only mildly coldy is it frowned upon to take them to activities?
