Women may have done half the labour but they didn't spend all their time weaving cloth and making clothing. You're forgetting about all the food preparation and preservation that women did. Women cooked meals, baked bread, preserved fruits and vegetables, and brewed beer, in addition to all the farm work they did (feeding chickens, collecting eggs, milking cows, working vegetable gardens, harvesting). Of course, women didn't do all of that work alone, they taught their children how to do it and supervised their labour. Large families were preferred because children are inexpensive (cheap to feed and clothe) relative to the labour they produce under proper supervision. Expensive entertainment and education for children was still centuries away.

Cooking was always divided in all cultures. Men too often left the village for long enough that they had to cook their own meals. Weaving and tailoring was often men's work.

of course harvest would be all hands on deck to farm, and preserving the harvest was part of that. However mostly that was not done.

women's work is mostly using a drop spindle - it took every woman in the village 10-12 hours a day, every day, working a drop spinele to get enough thread for their clothing. This was however an activity compatible with stopping to nurse a baby or otherwise care for kids.

you are thinking 1800s when the spinning jenny made thread in a factory. Or slightly before then when the spinning wheel (which should have been invented 1000 years before it did if inventors thought about it at all) which greatly freed up women's lives.

not to say that women couldn't do other the things. Different cultures had different splits. but most were making thread - we know because we know how much work that takes and how much clothing someone had (not much!)
