Have them do household chores and get them involved in cooking.
Learning to self care is as important as any formal schooling.
Cooking and food safety...
Wash hand before you start
Wash hand and cutting boards after handling meats
Wash hand before emptying dishwasher
Etc
Totally agree.
Schools used to teach useful skills, even if those skills were sort of reserved for ‘boy’ or ‘girl’ skills.
Instead of making a class of skills everyone needed to learn (condoms on bananas or cucumbers doesn’t really count as a life skill.) they stopped teaching skills altogether.
Balancing your checking account, cooking 2 or 3 simple meals, 2 or 3 more complex meals, changing a tire, checking your oil/etc, those should be taught. Sadly 2 parents work and don’t have the time for that.
