YOU! Your husband! Your mother-in-law! Your dog! Okay, maybe not, but you get the picture. Anyone can use a fitted. No pins, no snappi, no folding necessary. It's truly a "just add water" diaper. The key thing to remember when using a fitted is ALWAYS USE A COVER. Just because it looks like an AIO or a pocket diaper does not mean that it has the water proof layer. We'll talk more about covers later in the month.
