My SIL, now aged 30, was anorexic in her teens then after having her DD struggled with being overweight for a number of years. She is now a healthy weight and has been for some time. She was widowed 7 years ago and understandably depended on her mother a lot for help with childcare etc, as a result my DN is very close to her gran and spends a lot of time there (a lot of weekends, 3/4 evenings a week).
Problem is SILS mother cooks nothing but processed food, everythng is breaded and fried, usually served with chips and the woman doesnt seem to have heard of vegetables! DN has over the past 3 years put on a lot of weight and there is no sign that SIL is addressing the issue in any way.
She has had a difficult relationship with her mother since childhood and I think doesn't want to rock the boat now they are getting along so much better. AIBU to think she should put her childs health and happiness above fer mothers feeling and stop DN from spending her time there? And is there a tactful way I can raise DNs weight problem with SIL without causing offence?
