I was born in the late 80s / childhood in the 90s just for context as I hope these days this doesn't happen.
When I was about 8 years old I went for a sleepover at a good friends house (had been on multiple sleepovers before but this one stands out the most). In the morning we had Rice Krispies with milk for breakfast. I said I didn't eat my cereal with milk but she forced me to eat it. I remember crying and gagging over the cereal bowl and she wouldn't let me leave without eating it. I managed a couple of spoonfuls before she gave up.
Then when my mum came to pick me up and I told her what happened, she didn't take my side or defend me (which is for a whole other thread!).
As a mum of two, I can't imagine doing anything like this to my own DC let alone other children!
