I've got two kids and I work from home. If you really really need to focus, the get out of the house. Even with someone watching your small kids at the house, your lizard brain is still monitoring ALL the noise in the house, expecting some kind of disaster. (Your kids will be at home around the clock for the first year, or three.)
My (awful) hack is that I stay up really late while the house is quiet.
As a first time dad, do as many diapers as you can, wash and dry all of the bottles and/or pumping stuff you can, get the kid in and out of the car as much as you can, and just do everything you possibly can. No matter how exhausting it is, it's orders of magnitude easier than pregnancy, birth, and the first year for your wife. She'll definitely appreciate it, and it'll really help your marriage.
