I disagree with this too. It's nowt to do with stricter parenting, as the majority of obese children have obese parents - ones who can't be arsed making home cooked food and instead rely on processed ready-cooked meals or cook-in sauces and fast food.
There's a reason I don't want to have kids, I am not mature/ready/capable enough. When (if) I will be one day, and if I feel like it, will try and adopt one. No reason to add another soul to this overcrowded planet, plenty of kids out there who need help.
/end of mature discussion, it's a Saturday after all!
