If I leave him to it, he counts standing in his pants with the toothbrush in his mouth as having brushed his teeth. He knows how to do it properly, he just can't be bothered. Besides if he has a friend for a sleepover, I brush them for him. He is laid back and happy for me to do it. I feel better knowing they're brushed properly as he had to having a filling last year after a stint of him brushing them.
We stayed at MILs yesterday and she horrified to see me brushing them for him. She said he, and even my 4 year old, should be brushing their teeth themselves. I agree they should but they don't do it properly and don't mind me doing it so I don't see the problem. Aibu to still be brushing them?
