SP fleece. 2-ply and 1-ply confusion!

[papal]

Hey girls.. I am a bit confused.

I have 2 SP fleeces.. one is buttery soft and 2-ply.. the other is soft (but not buttery) and 1-ply (but the fleece seems thicker).
Which is better for NIGHTS? The thicker or the 2-ply?! I can't test because they are too small now!

Thanks!

You need to use the 2-ply for naps, because it's much thicker.

As an added note: I know the 2-ply are softer, but I personally prefer the 1-ply because it's so much trimmer, stretchy, and fits a big-baby much longer. The 1-ply covers I have still fit on the tightest snap setting for both waist and thighs! (and Joshua is 31 lbs.) The 2-ply fit on the 2nd snap setting for both waist and thighs, and they are snug then. Probably because the added bulk takes up space, and they stretch less.
