I'm the same, my step son is 9 stone 3 and 10 years old, he's on the 99th centile and is visibly very big. I always do healthy food when he comes over for dinner (twice a week). I just think as long as I am doing my bit then I will carry no guilt! Whatever his mum or whoever else does is up to them. I've tried to talk to my partner about it but he gets extremely defensive. We were at a fayre once, my little boy wanted to go for a wee so just him and I walked off to find a toilet, he wanted an ice cream when he saw the van so I got him one but we ate it away from my partner and step son so i didnt have to say yes to my son and no to his. I thought it was the kindest thing to do but when asked what took so long I said I got him an ice cream. I was told I was out of order and my partner marched his son straight over to get him one. Personally I couldn't believe it, we argued and it was me that was the bad guy although I'd tried to do what I thought was the right thing.
@Emily it’s so hard isn’t it?! I also have a SD who is the complete opposite, she’s very athletic, active etc and we don’t want to seem to favour one of them but she actually burns off the calories where as SS has a very inactive lifestyle, at bio mums he spends all his time upstairs playing games and eating sweets etc. I just get so frustrated that bio mum doesn’t see it as a problem especially with SS going to “big school” in sept, I am worried about bullying. I am larger and got horrendously bullied. Feel like I can’t win as we encourage healthy eating and he resents coming over as he doesn’t have to eat vegetables at his bio mums
I am in a similar situation with my SS. He is 10 and weighs 10.5 stone and is in adult medium clothes. We try and encourage him to be active and not over eat but at his bio mums house there are no real rules and she massively over feeds him or lets him over eat to the point he has been sick multiple times. We have brought this up with her several times and she does not see it as a problem. It has caused several arguments and it can be really tense at times. It is something you or maybe his dad can mention but unfortunately I wouldn’t expect there to be drastic changes (from personal experience). The school nurse might be an option, but this could be overruled if bio mum is classed as main parent and doesn’t want to take it further. We try and do the best we can and are trying to make peace with that (at the moment) it’s all we can do. I hope you have more success than us for your SD sake x
