When my daughter was born, my dad was not yet fully retired. Mom jumped at the chance to watch her, but Dad wanted to retain full freedom, knowing he was to retire soon. Mom said "well, you'll have to go to Florida without me because I have a granddaughter". They ended up taking her 3 days a week and my ex-wife worked from home for 2 days a week for the first year. At one year, we put her in daycare 2 days a week and my parents kept the other 3. The daycare was flexible, and we could go to 5 days any time we wanted. That allowed my parents to travel whenever they wanted without us having to use vacation days. It also helped her socialize and learn to share with other kids.
When my son was born, my wife couldn't work from home, so he did 2 days in daycare and 3 with mom and dad. (Both retired by then, 13 years later) Again, daycare could be 2-5 days per week as needed so we had flexibility. When he turned 3, we moved him to a different daycare for 3 days a week. This one was more like pre-school with a lot more learning activities, he needed the extra stimulation but prefers grandmas. (who wouldn't)
We never paid my parent's, they said that they wanted something to keep them busy during their retirement anyway. They even furnished a baby's room and stocked up on toys and supplies. We offered many times, but they would hear none of it. My kid's lives have been so enriched by the time they spent with their grandparents, and vice versa, so I don't feel too bad.
My daughter eventually got on and off the school bus at her daycare, something to consider if you are not home during those times. My son's daycare is not in our school district, so we will have to change again in another year. What do do after school but before you are home from work is a challenge, some places offer this and others do not.
As for resources, most hospitals offer free Infant First Aid and CPR classes. TAKE THEM. Knowing what to do with a choking baby will come in handy and will lower your stress levels a lot. Other than that, ask. Heck, I'll tell you whatever I can. And decide RIGHT NOW that you are going to be a 100% dad. I shared every responsibility when my daughter was born, and when I got divorced that really came in handy because I could do anything. Not that I would wish that on you of course, my point is that the dads who leave all the "baby raisin' stuff" to mom are missing out...and missing the point.
