Had my sister in law over yesterday with all of us (me, DH and DS 6 and 4.)
Whilst I was making lunch SIL was playing with DC aged 4 with a small shopping trolley. I could hear shrieks of playfulness but nothing more and the day carried on.
Today I got a text from SIL with a photo of a bruise saying my DC had done that yesterday. I was taken aback as it's a small bruise, nothing had been mentioned yesterday and DC is four. It wouldn't have been done in violence and if there was an issue I believed friend should have said something yesterday.
I apologised and said I didn't realise they were hurt and SIL has said it hurts now but will be better soon. AIBU to find this all rather strange?
