I have a friend who travels a decent amount and keeps really long hours. Her husband is gone 4-5 days per week. Every week. They hired a nanny at birth who is still around a decade plus later. She is older, has a lot of flexibility, does not live with the family but can stay as needed. She is very well paid, gets excellent health insurance, transportation, etc. And now that the kids are in school FT she has a considerable amount of free time.
If you can swing that financially, and you are comfortable with that lifestyle, it's doable. Not my cup of tea but my friend and her family are happy and the whole setup works for them. Be prepared to shell out six figures when all is said and done.
