My 5 YO DN tried to put her hand in boiling water the other day to fish out a dummy i had just put in to clean for my DS i told her that she would burn herself and not to do it, her response was i don't mind i like hot water it's fine to put my hand in. I explained that boiling water is not like having a hot bath it will hurt you very badly so it was not a good idea to go putting your hands in it or anything hot like kettle cooker sterliser but she said it is a good idea because she will do it quick and it won't hurt.
Obviously i was very worried she's goin to start touching hot things so i asked if she would like to see a picture of someone who has burned thier hand badly she said yes so i googled showed her and she agreed no it was not a good idea and she won't do it all sorted. Now my mum has told me i should never have shown her these pictures as they might have scared her but that was sort of the point to show her how badly she could be hurt.
AIBU in showing her theses should i just have explained and left it there.
