yeah I don't know. It depends on the child really.
Hannah just turned 7 (I know... I can't believe it either lol) and there are certain things she can do and can't do. She can't vacuum... she doesn't have the leverage or the upper body strength lol with my vacuum it's all I can do to push that sucker around lol.
She can and does make her bed... and mine actually LOL. I never taught her this because I think making beds is stupid and pointless so I don't do it. But she likes a nicely made bed lol so she'll make hers and then go in and make mine *shrug*
she unloads dishes but not the plates. She can't reach the cupboard without crawling up on the counter and that's well and good when she's just getting a snack but I really would rather her not try to crawl up on my counter with my breakable dishes haha. so she puts away Tupperware, silverware, anything she can reach.
She made pancakes the other day all by herself
I just helped getting ingredients down and helping her decipher the recipe. she did all the measuring, mixing, pouring and cooking all on her own with a little vocal guidance from me when she wasn't sure what to do or how to do it. BUT she enjoys cooking and loves cooking shows. If she didn't show an interest in it... I wouldn't expect her to cook things lol.
so it really depends... and she's 7
