Answer: Well I would tell her that her child may feel some pain at first but she will feel better right after the braces are done being put on and then she can get herself a smoothie or something like that and she will feel all good once her teeth are all good and fixed but DO NOT TELL HER SHES GETTING THE BRACES BECAUSE HER TEETH ARE ALL JACKED UP. This will lower the self esteem of the kid and will less likely want her to get the braces she wants to feel good about herself and tell her she gets to pick out the colors talk about most of the positives in the beginning then talk about some of the negatives such as not being able to eat some the things you love but also leave some good positive things at the end so when she leaves she and her mother will both feel excited about the braces, and one less thing tell the mom that if it is FINANCIALLY HARD they or you can find help for it.
Explanation: Well I think the best thing is to list out the pros and cons on getting braces so that she and her kid will feel better about the whole situation and it doesn't put anymore stress on the mom or kid.
