How to address a problem with a friends child without insulting them.
My friend's child is seven and I've been staying at their house for the past couple of weeks and I have noticed that he sucks his thumb almost all of the day.
At the dinner table, watching TV, just walking around the house.
The only time I see him not sucking his thumb is when he's doing something active; playing with friends, in the pool, etc.
At first I thought it was just a little strange until I researched how old most kids quit sucking their thumbs. My result was around one, and that most parents should incourage their children to stop by four if they haven't already quit. Prolonged thumb sucking can cause major dental problems!
Now I'd like to bring this up with her, but I am scared I might offend her, for I am much younger and have no children, I.E. I'm not very experienced with children. What would be a good approach on bringing this up with her?
