TBH... babies fucking suck. It's true. I love my son but holy shit I've never wanted to sever my own head more times than while that "baby" stage was in.
Children however are pretty cool with the exception of the being a parent part. It's not all hot wheels and food fights sadly. Eventually the hammer has to come down on little man but it's an experience that I'd never give back and genuinely feel I've grown tremendously for the better because of him being born.
Other peoples kids suck because people suck. Your own kids, with proper "parent mode" time, will turn out to be respectful, trustworthy little shits that you don't fully regret having
TL;DR Baby's suck. It's hard ass work being mom & dad. Don't do it unless you're ready for a game changer.
