How many pairs of socks should a 2 year old have?

Mine has almost 40.  That's too much, isn't it?  LOL.  Today is a miserable, rainy, can't go anywhere type of day so we figured we would pull down the summer clothes from the attic, take out what the girls have outgrown and put those away; basically get organized for when spring and summer finally appear.  We have enough clothes for these children to open up a pretty nice consignment shop.  Ay yi yi.  With three girls in the house, I'm not really complaining.  I'm grateful that I have enough that the younger ones have full wardrobes until they are at least 6 years old thanks to what their older sister has accumulated.  And my niece gets in on the deal too since she can wear what the 2 year old won't be ready for until next year.  So everybody is definitely getting their money's worth out of these clothes.  With that said, it is a lot of work to keep up on cycling these clothes through the right seasons and sizes.  If anybody has any tips that would make this easier, I'm all ears!
