My toddler is constantly sent home from nursery at the moment (every other week the last few weeks) with something or other. Recently we've had hand foot and mouth, tonsillitis, a vomit bug, temperature...I am so fed up of it and starting to worry why they keep catching things. Is it normal and can I do anything about it to try to prevent more sickness? Also it's so frustrating when we are paying for the childcare. Thanks
