Nesting?

After school today I got the urge to go through everyone's clothes, toss what is worn out, hand down what still looks good, count and see what we have too much of (always t-shirts), and make a list of what needs to be bought or replaced. I looked up all kinds of lists online to see how many shirts, pants, dresses, etc...the kids really need, I did three loads of laundry today, and I'm already halfway through this whole process by bedtime tonight. I'd say it was a pregnant/nesting thing, but it could also be because I don't remember the last time that I did this although I'm pretty sure I did it regularly up until the time the scales tipped in favor of there being more kids than adults at home. Up next...toy sorting/purging and, I suspect, much wailing and gnashing of teeth before it's all said and done.
