I originally thought it was, but when talking to people, apparently it's fine because getting the time off work is a bitch and the old "it's good for kids to get colds, it builds their immunity!".
That may be true, but I have a baby with neonatal rhinitis, feeding difficulties and asthma. What might be a mild cold in other children ends up as a chest infection and possible hospitalisation. I know people will say "well that's your problem", but is it unreasonable to expect people to think that there may be kids who are vulnerable or in contact with vulnerable people, and that sending your germ ridden kid in could have real dire consequences? I don't see why my son should have to not go to nursery, which he enjoys, because of something he can't help.
I wouldn't send my son in knowing he was ill, because that's how germs spread. AIBU to ask the nursery to notify me if there are germs going round so I can decide if my son needs to stay home?
