Congratulations of being a grandpa soon!
Home birth reminds me of how my parents were born in their WW2 time, but that was because Labour specialty centers weren't around yet.
If your daughter is healthy with no underlying complications, guess home birth will be less trauma.
All my nieces and nephew were born in a special Labour center where it is not part of a large hospital and with professional care. Now we even have special confinement centers post giving birth so that mommy and baby has special dietary care and family are not overwhelmed with adjusting the baby's new body clock, especially for the husbands who are still working and does not have many paternity leaves.
