Congratulations!
I know you are sleep-deprived now, but do try to enjoy how little and precious he is while he mainly sleeps/eats/pees/poops all the time now. Sure, you’ll get a golden shower a few times (you learn quickly to try to cover it with a towel or new diaper) but you’ll laugh it off in a few months. I have a 20 month old son now and I’m surprised on how I almost forget how small he was as a newborn.
