What do most American women do after having a kid, quit their job? You can't put a newbord in daycare can you?
You can. Many daycares take babies from six weeks onwards. I cannot imagine how it must feel as a parent to do that at six weeks, but plenty do.
We felt bad when our second kid started daycare at 18 months.
Or just take barely enough unpaid leave (or draw on other pools of paid leave, which are usually tiny anyway and may have been eaten into over various pregnancy-related issues and appointments already) to get back on their feet and head back in, leaving the baby with a cheap unlicensed daycare down the street (maybe fine, maybe, uh, not, but not like there are other options on a limited budget) or older relative or whoever :-/
