You'll find they're much different from girls, even when they're two!
An infallible truth for sure. Girls are MUCH more difficult. Boys break EVERYTHING YOU HAVE, stuff you didn't realize could break, like rocks, or Craftsman tools. One of my sons, I was showing him a machinegun in my collection that had been in WWII, I turned my back on him for 3 seconds, he broke it. NO not permanently, just jammed the bolt carrier back on an MP-40, maybe the most durable weapon you've ever seen. It's fine, but how does a 6 yr old find a way to do that? We call him Wreck-o-babe and with his litle brother, wreck-o-brothers. Enjoy, make them pay the daily hug tax, they'll always love you.
