"at some point, you will pick up your child for the last time, then set them down and not in the moment realize that you will never pick them up again"

I pick up my kids all the time because of this. My wife thinks I'm spoiling them, but there's a very limited period of picking them up.

Even the span of time where they're interested in you is limited. They have a fascination with their parents in the first few months, and then they start looking at things, and a few years later, at friends, then the material world. After that, you're happy just to get a call or visit. The new generation complains that homeownership is a distant dream, but I think living with parents may be a blessing in disguise.
