A child 3yrs told me she had been sick this morning. The parent didn't mention it and looking back the drop off was quicker than usual. I sympathised and asked her if she was feeling alright now before asking if it was before or after breakfast. She said it was before and then listed what she had eaten. I thought perhaps she coughed and had something in her mouth and not really sick. Decided to stay in all day to be on the safe side.I also have my son 10m and the child's sibling 6m to care for. She was hungry at lunch so I cooked plain chicken and rice which she tucked into. On collection I told mum what dc had said and she bluffed about skirting the issue and slipped in '5 to 7 too late to let work know' before moving on. I know i should grow a backbone and respond but I didn't. So I'm probably upset with myself as well as upset being treated like this, let alone their child. So pleased I stayed at home keeping her in the warm. At the moment my dh is based away from home, so I am alone all week with my 5 children, so I am concerned if this is a bug. What would you do??
