What does "half kid" mean in this context? Stillbirth? Unborn child? A pet?
The context is from a book called The Subtle Art of Not Giving a Fuck by Mark Manson.
Our culture today is obsessively focused on unrealistically positive expectations... Be happier. Be healthier. Be the best, better than the rest. Be smarter, faster, richer, sexier. Be perfect and amazing and crap out twelve-karat-gold nuggets before breakfast each morning while kissing your selfie-ready spouse and two and a half kids goodbye.
