Posting here for traffic, I'm at my wits end and DP is leaving it all to me.
DP's DGD is 3 years older than my DD- we had DC at completely different life stages! DD is with her dad one night a week and EOW, with us the rest of the time. We have DGD and DGSs from one of DP's DC overnight regularly. Usually 1-2 nights a week but sometimes up to 4.
DGD has been referred to CAMHS eating disorder services. No diagnosis yet but lost a lot of weight, restricting food, struggling with body image etc.
DD is overweight and currently has a really awful relationship with food, and I'm finding it harder and harder to support DGD when she's here without feeling like I'm failing her. DD's dad is useless and feeds her rubbish when she's with him, so I really do need to be trying to tackle her weight while she's with us. Ideally without making her aware of it. Both of them have issues with portion sizes but in opposite ways, and I'm finding we're allowing DD to overeat in treading carefully around DGD.
I don't know how to do the right thing for both of them when they're both here at the same time. DP thinks we should focus on DGD and just leave DD be, but that feels like setting her up for a lifetime of problems. I feel like there has to be a better balance but I don't know what it is.
