Childcare- More than half. Mainly taxi-ing and playing footie these days.
Gardening- 99%. I choose the plants, play with the vegetable garden app to plan and buy seeds, then can't find my wellies and he had to do it all. And it gets hot here so usually by mid June I am flopped on the sofa till September moaning quietly. I do occasionally mow the lawn, but DH doesn't like the fact my shoes make spike holes everywhere. Personally I think that is aeration, but there is no pleasing some people with offers of two jobs done for the price of one.
Shopping- I do the big shops, maybe once a month ish. He does all the in between "oh crap I forgot to get black bags!", "I need foil! Where is my foil!! Somebody has stolen my foil!!"" and stuff like milk, fresh fruit and veg etc.
Housework - It has taken 18 years of being blunt and immovable (plus some shouting) about it not being exclusively my mess/dust/laundry etc to get past the training the PILs gave him (ie, the bepenised might as well chop their willy off if they do "women's work"). He does the jobs I hate mainly. Like collecting washing up from other downstairs rooms. And finding, bringing down, sorting, hanging and putting away the washing. Plus all things to do with the disposal of rubbish and finding my broom (which like my foil keeps walking off), and dealing with all the hardpaved areas outside.
DS does washing maching, dishwasher, living room tidy/hoover/mop and his bedroom. I do the rest. for now. DS is getting a bathroom soon. Damned if any future partner of his is going to have to struggle for years like I had to in order to get past the idea that "boys don't clean house".
