Sorry for the crudely worded subject but I couldn't think what else to call them.
DD (7) often has round bruise like marks on her arm which I found a bit odd but thought she was just falling over at school a lot. But the other day I saw a red mark on her arm and looked closer and realised she is sucking on her arm. From the marks on her arm I would say she normally does it on her inside forearm but this time it was on the inside of her upper arm.
I told her she shouldn't do that as she is damaging her skin and she said ok but today I saw another one. I asked why she does it and she said she likes the taste
. Not sure what to do really but it can't be good to be doing this all the time.
What should I do/say?
