She used to work fulltime but since my son was born, or actually 5-6 months before that, she stopped working as it didn't make much sense otherwise. Paying a maid would easily cost 12-15K a month (even it's less, than still additional transport costs etc). Even if she would then earn 25K a month, didn't make much sense to me for my son to grow up with some random maid instead of her.
So long story short, she basically takes care of everything in the house and I earn the money. Now my son goes to school she does do some eCommerce business. I see many Thai with maids while their parents (grandparents of child) are home too, but not look after their own kid, the kid seems to be more close with the maid than it is with their own parents and grandparents, not really see the logic unless you earn 30-40K after paying the maid, more.
