I've got a 4 year old boy and 2 year old twins, boy and a girl. I'll put a picture up when I'm at my computer
The twins love helping with bottling. Big boy only becomes interested once the twins start helping. They're a massive pain in the arse! But they love dunking the bottles in the StarSan bucket and emptying.
Little boy eats grains out of the bucket by the handful so I've had to move the buckets up higher. All 3 of them saw that crown lager ad with the barley farmer and started saying "he's making beer" as soon as they saw the grain.
All are obsessed with doughing in, and my wife seems to manage to disappear at the exact moment. It's actually a source of tension because it's ******* dangerous to have 3 kids around close to 40 litres of 70 degree water while I have my hands full.
So I'm back to brewing when they're asleep and just bottling with the kids.
As chaotic as they make it, I love that they're interested in it.
