knitted and crocheted wool. For that reason, I use fitteds. I like having something to change into when I want a break from Fuzzi Bunz. Sometimes, I want baby's butt to breathe a little more so I use the fitteds. I've only just begun to stand using them since I found some great fleece-topped doublers. Baby is a heavy wetter and it made no since to put a fitted on before the doublers came because I'd just be taking it right back off again. Now, with the doublers, we can even go coverless for awhile.
The fitteds I have are Cuddlebuns one size so they are a great investment for me.
I reach for the fbs first and then fitteds. Now that daycare is using the fb, I find it better to use the fitteds in the evenings and on weekends. We still use fb at night.
If I didn't have a fascination with wool soakers/longies, I wouldn't use fitteds. I will only buy patterned fitteds because I love fabric so much and plain fitteds are such a waste to me.
First and foremost, fitteds give me an excuse to buy more wool
