Every parent thinks the same thing but I finally get it! I'm with my 2 day old daughter and she is the cutest nugget! The wife is an absolute hero and legend I'm watching her so she can sleep. I can't lie, I am sleep deprived and had moments of sheer anxiety during troublesome bouts. But moments like these, the first time we saw her, and her beautiful eyes looking in mine. All that good stuff seems incomparably blissful. As I type this with 1 hand at 3am on 4 hours of naps (not even sleep), I can't help but smile as my girls get their beauty rest.
For any new parent struggling or scared, I understand now. It's a level of emotion I haven't experienced for a long time. Don't be afraid to seek advice/help. You're not alone in this feeling. I found that just calling someone experienced for dumb questions makes you feel much less alone in this adventure. Stay strong, dads!
