Also a father, and I don't see it as a case of positives and negatives, rather how much energy you're putting into it.

There are many methods of minimizing the effort you're putting in and you can make it relatively easy, but like with everything it's a tradeoff.

Food is one major point. You can introduce a baby to solids early on and practice the BLW method, or you could just spoon feed them with ready-to-eat baby products - there's an order of magnitude difference in effort between those two approaches.

One thing I learned from this experience is that it's beyond the capabilities of a normal human couple to apply all the fancy, high-effort parenting methods - you'd need at least two grandparents cover just the more popular ones.
