Hi Andy, just reading your situation for the first time today.
I want to ask you why your wife is taking ten months off, perhaps 4 months and then go back to work for a few days a week. I think you may be overwhelmed with the news at the moment and missed this strategy. Baby needs a good start and 4 months is a good one. By that time your wife may be ready for a few days at work for some mental stimulation while a “grandma” takes care of your treasure. We were in a similar situation but no family so we bought a small business so I could work from home. The business bought in $25k per year.
Accounting, typing resumes, Ironing whatever it takes and remember its temporary
