Just that really, turns out that DH has been putting adult Toothpaste on DS 3 toothbrush for over a month now. We have milk teeth Toothpaste in the house which he has been using for the 1 year old, but apparently everytime he's done morning or night teeth brushing over the last month or so he has been using adult Toothpaste on DS3. He said he thought he'd outgrown the baby one. To be clear, he still has all milk teeth, he's 3!
AIBU to think DH is a bit batshit for doing this and needs to stop immediately!?
