I've been thinking about starting a Tumblr account for some of the many Pro Tips™ I'm learning from raising a baby. I'm sure there are about 10,000 more that I will learn in the next month alone.
Like "when your baby boy starts peeing during a diaper change, you can either let the stream hit the nice carpet and cause a stain, or use your hand (which is much easier to clean) as a deflection shield to keep everything in the waterproof changing pad liner." Apparently this also makes your wife laugh.
It's like babies know when the worst time is to spit up, go potty, and scream—and intentionally do those things at that time. I think they're just playing us parents all for fools.
But they're so darn cute, it's impossible to get angry.
