Hi, so I'm not at this stage yet but I have been thinking when I'm ready to have kids I don't really want to be working full time and sending my kids to daycare but -
You don't have to. You could work full-time and your husband could be a stay-at-home father.
I work 20hr pw in a home business, and have about another 40hr pw of child and home stuff. My wife's a professional, she does 40hr pw in the office and another 20hr pw of child and home stuff. Her earning potential is higher than mine, but the real reason is that I'm a domestic person and she's not.
Unfortunately our society assumes it must be the woman. Women have to have the babies, but once the baby comes out a man can do everything except breastfeed, and with expressing he can do a lot of that work, too. Not all women are willing or able to breastfeed, but even if they are, that's still just 6 months of multiple feeds a day, after that the baby gets onto solids and the breastfeeds decline, so with expressing the woman can do whatever paid work hours she likes, and the man can take care of everything else at home. Too often the fact of the birth and the 6 months or so afterwards with the woman at home, sheer inertia keeps the family going that way and 5 years later she's still there doing the dishes.
It need not be so.
Talking to and watching other families, I think it works best for most to have 1.0-1.5 full-time equivalent paid jobs between them. This could be one maniac doing 60hr pw or 2 people doing 30hr pw or 40 and 20, for the 1.5x ones, and of course many combinations making up 40-59hr pw, too.
People tend to look just at the income, but as you note, childcare does cost money, so the household as a whole isn't necessarily better off financially. And someone at home has other benefits. If you're both doing 40hr pw jobs then meals will be rushed, more packaged stuff and junk. The house will be messier, and everyone will be more stressed as a result. There are many nonfinancial benefits to having someone at home most of the time. But again: this doesn't have to be the woman.
If you don't talk about it with your husband, then sheer inertia will mean it'll be you at home. But on talking with him and having a back-and-forth considering money and stress and what sort of family home you want to have, it may turn out to be him. Or perhaps you'll both do 20-30hr pw paid work and split the household stuff equally. There are zillions of ways to do it. Think about it and discuss it with the guy.
I actually think it's better to have the man at home than the woman.
