I have namechanged for this. I've been pondering whether to tell him?
This morning I sterilised my mooncup (hasn't been sterilised since last period) in boiling water in a mug. Used the tongs to get it out and took it upstairs but in rush of getting DCs out of the door for school forgot to get rid of the boiling water and put the mug in the dishwasher.
DH has recently taken to drinking hot water plain - he alternates it with coffee as he says it makes his breath better.
He drank the mooncup water and was finishing the mug as he left for work.
There's no point in telling him is there?
