As a proud father myself, it's my pleasure to congratulate you on your baby. You'll hear plenty of congratulations, and they're all well and good, but what few people will emphasize is how brutally sleep-deprived and stressed you will be for months on end. Man up and just ride it out. It's all part of the deal. Yeah, it sucks, but before you know it, that little newborn will be a toddler and then a teenager, so enjoy the moments for what they are, even if it means changing diapers and cleaning vomit at 4 in the morning, you'll never get back those precious moments. And indeed they are precious, despite how they may appear otherwise.
Cheers!
