I had mostly fitteds with my daughter that I made from Wazoodle kits (little green bear). However, I tried to be all cute and crafty and add a pretty layer to the outside... so, the pretty layer is disintegrating. The diapers still work, but the outer layer is sort falling apart. The small/newborn ones, however, are just fine, as they only fit her for 2 months.
We've bought some more flip inserts and covers and are planning to go that route this time... but I still want some fitteds, and happened across the GMD workhorse sale. Now I kinda want some... but I don't know what sizes. I'm thinking just a half dozen of each, so I have some variety, and so I have something to reliably contain poo when out and about. If the ones I have are good through 2 months or so (I don't remember how much she weighed when we switched to the mediums... maybe 12ish?), and I plan to CD through somewhere around 20-22 months (we potty trained my daughter around then, and plan to do the same), can I get away with buying just two sizes? Smalls and Mediums, or Mediums and Larges? I haven't used GMDs before, so any sizing advice is appreciated.
