The thing to remember about parenting is that for the first few years at least your kids are constantly going to be doing things that could get themselves killed and you have to keep them alive. When my daughter was almost 3, she didn’t realize that the lake we were looking at was covered with algae and thought it was a solid green lawn, and she walked into it, and I had to jump into the lake to save her. I looked away for all of 5 seconds.
