it very much depends on how prepared the parents are. if you or your partner grew up with a lot of siblings you have plenty of examples from your own childhood to draw on that make things easier.

i didn't have that, so i struggled, especially in the beginning, not because it felt hard, but simply because i didn't know what to do. the mechanics are easy to learn, feeding, changing, sleep, etc, but beyond that i simply had no examples to draw on. but i was able to compensate that with continuously being aware that this is what i wanted. i chose this adventure, and i was not going to despair over making that choice, nor would i regret it.

but we were also lucky, and our kids were not fussy and slept well. they got plenty of breastfeeding because nobody told my wife when or how to stop and she didn't complain, so she stopped when the kids were ready on their own.
