Lining up to pay our entrance fees and a mum with toddler and preschooler come in. Toddler is covered in sick. Mum announces 'she's been sick in the car getting here, just going to clean her up' and ushers kids to the loos. Reappears (toddler in fresh clothes), they pay and join the group. Toddler running around playing, apparently ok now although I overhear her mum telling friend she doesn't know why she was sick.
AIBU to think it's idiotic and selfish to take your child into playgroup when they've just vomited? If it's a bug you risk infecting all the other toddlers and babies 
Would you have said something to the mum?
