Yes. None of those scenarios is uncommon.
I have run fiduciary financial planning programs pro bono for lower income people.
Here are some actual steps responsible people have taken before ttc:
Have zero debt
Live on one income and save the other regardless of how restrictive, in case one partner becomes redundant or disabled
Obtain employment on opposite shifts to obviate the need for childcare
Prioritise the purchase of life and disability insurance
Always have a backup income stream on the go be it Uber, a lodger, ironing, babysitting or supermarket shifts, just in case
Be willing to live without car, holidays or restaurant meals in the early years
Be open to communal or multigenerational living to pool resources
Etc.
People unwilling to do any or all of the above to make their situation work, but who expect endless and unconditional support from society, employers and taxpayers, don’t impress me.
It’s not brain surgery. Most people’s lives include some combo of unemployment, illness, disability, divorce, economic recession, death and unexpected events. Proceeding based always on the assumption one can be bailed out by others is unwise.
