Who thought this up?

My friends Josh and Susan are having a baby, how fun! So I thought I would sprinkle a little Carlyn OCD into their lives  before they welcome baby Hazel to the 757. Since I can't teach her how to dance or vacuum yet I settled for prepping her wardrobe. Clearly I was under qualified. 

Pictured above is my attempt to organize choices by size, sleeve length and category. Each time I found a new size I started a new row, the rows kept going and going.  I felt like I was trying to organize a super 1000 box of crayolas by primary color. Is salmon with pink or orange? Is 3-6 month acceptable to put in the same pile as 6 months, or do the the white onesies go with pajamas or tights cause babies don't wear underwear. Baby sizes are stressful. Did they have a size committee that couldn't agree so they decided to use all of them?
I settled on piles of categories in labeled Ziploc bags. If this is any indication of how complicated the baby will be I feel like I should have saved my labels and bought them as much coffee as possible.
