Yes, for example I married my partner who was on an F1 visa, which is a non-immigrant visa, and we were able to easily adjust his status to the GC (this is faster than the K1 process)
Only if you have more than 250k in the account - the first 250k is insured by the government and if the bank fails is typically paid back in less than a week.
We use YNAB, a program run by a small-ish team in (i think?) Utah. It's forward looking budgeting, but with the expectation that you may adjust mid-month. It imports transactions from my banks through a third party, and that "usually" works. It doesn't cover investment accounts, we just use it to manage cash flow and monthly planning.
There are essentially zero kids "available" to adopt outside of foster care. And foster care is (correctly imo) focused on reuniting children with their parents when possible, so the typical case of adoption being possible is when the parents are truly unsafe.
Exclusively breastfeeding is very challenging to do while working, for one. Even at my megacorp with a dedicated space, a hospital grade pump, and 2 hrs a day dedicated only to that, it was a substantial hit to supply. Considering that most women don't have those amenities and support I'm not surprised they don't breastfeed exclusively after their mat leave (for most women in the US, 6 weeks unpaid)
Not to mention - it can be painful (if I had no option of course I would endure pain for my child, but there is no shame in looking for something less painful) or the baby can not learn to latch (formerly known as "failure to thrive" and a driver of infant mortality)
