Please remember to let us know if your child is unwell and not able to attend pre-school. If they only have a cough or cold but are generally feeling OK, then they can attend pre-school. If your child has suffered from sickness or diarrhoea, please DO NOTÂ return to pre-school until 48 hours after final bout. If your child has got headlice, they may attend once treatment has started. For information about any other illness exclusions that you are unsure about, please contact Pre-School.
