My guess is that some powerful hormones must be released or something after having a child to make people think that they are enjoying their life even though an outside observer can view their immense suffering.

It’s partly that, and partly that the brain needs sleep too form memories and to think things through to conclusion, so we’re all a little delusional and don’t really remember how hard the early part was.

(I adore my kids!)

Pro tip: smell their heads as often as possible. There’s all kinds of healthy chemical bonding that comes from that delightful fresh baby head smell.
