DS (4) has been sleeping most of the day and vomiting on and off. No other symptoms. I called Nursery to say he was going to be off until Monday. (48 hour vommiting rule). They have asked if we can get him tested as it is how Covid classically presents in children. If this true? I can't see anything online to suggest this. I called the GP due to the constant sleeping and lethargy. She also mentioned Covid and now I am worried about what I should do about him and his 7 year old brother.
