I would be furious. My aunt used to force me to sit and finish my food and now I have issues with food. Never ever force someone to finish everything, that’s abuse.
Jesus…. All these comments. I’m thinking y’all should just keep your kids home. I learned at a very young age that when u go to a friends house there will be different rules then at my own home. Even different rules between my house and my dads house. I was put in time out by other ppls parents, and disciplined right along with whatever friend I got in trouble with, and I am not traumatized. I got more discipline by other ppls parents then my own and I was better behaved at their house for it.
I wouldn’t say I was forced to eat everything on my plate growing up but I was forced to eat food I didn’t like. I don’t force my kids to eat anything. I give them a bite to try and if they don’t like it fine. I fix what I know they like and something they need to try. I’d be livid if someone forced my kid to eat anything. I’d never do that to someone else’s kid.
I’d also be livid. Luckily my son eats everything so I don’t have that struggle. His best friend only eats Steak and Shake chili from the can heated for thirty seconds only in the microwave. 
Sounds like she’s gas lighting you because she knows she’s in the wrong. I’d politely call or text her and say…
“hey i understand we don’t see eye to eye on the situation but I would like to come to a middle ground here for the children’s sake since they’re such good friends. I understand and respect the rules you have set for your children and am not passing any judgement on how you run your household. Therefore I am respectful asking you not to force (your child’s name) to eat something she doesn’t like or want while she is in your care. I hope we can move forward from this Situation.”
Then maybe suggest a play date at the park or an indoor play center where you can attend as well and get to know the mom a little. I bet she just feels guilty and has a hard time excepting accountability.
Even without sensory issues that Mom was wrong. Disgusting to make that a rule. Easy way to give kids an unhealthy relationship with food at an early age. She should be teaching her child to listen to her body to understand when she is full.
Also did you know she was going to feed her dinner? My child has eaten at a friend’s house before but the parents always ask if it’s okay first.
I would’ve been shoving corn on the cob down her throat if she ever tried to force my daughter to eat I don’t care how long I’ve known her for or how good of friends they are! your child, was sobbing, because another adult tried force feeding them like what??? absolutely not!!! you have every right to be livid and you need to find your daughter someone to hang out with in neutral grounds. You just can’t trust other adults. 
This and the not allowing children to have their own cell phones on them are RED FLAGS. I wouldn’t trust the parent in either scenario. I woukd do play dares at your house or a park
Idc what are house rules are, you don’t force a child to eat, especially if it isn’t your own child. That’s sick imo
If thats her best friend then she can continue to be friends with the little girl but I would not allow her back at that house. I mean who does that? How would you feel comfortable forcing that baby to sit at a table and eat something she didn’t want. That’s crazy messed up.
That’s awful. And I don’t blame you one bit for not letting her go there again. They’ll just have to play at school, or wherever is not at the other kid’s house.
My son is a picky eater, no one forces my kids to do anything. That mom would be forced to swallow her teeth.
No child should be forced to eat or punished because they don’t regardless of any issues they may or may not have and I certainly wouldn’t let my child go to that friends again
Don’t like to say this and I’m ready for all the lecture but I agree with the friends mother. I think today’s society has too many excuses for kid’s behaviours. If your eating at someone’s house you eat what you get. If you can’t do that then eat at home. If the kid can’t eat something because of an allergy that’s different. If it’s not going to kill you then be polite and eat up.
