Fathers can also take paid paternity leave, usually you can split the leave with the mother however you want, and if you do you get a few months extra.
It's also typical that the father gets 3 weeks paid time off when a baby is born, to care for the family. I feel this was invaluable for me and my family.
I honestly find the US system inhumane, forcing mothers back into a job so soon, and a baby so young is just a tiny, vulnerable, little human. Too early to put them into daycare in my opinion, but I understand that many parents are forced to for financial reasons. The US healthcare really needs a big overhaul.
