How many of you have/would use them? I have 2 older kids, and i never used them, but looking for nursery stuff for this baby, all the sheet sets come with a pillow case for the cot, plus looking at a baby store yesterday, every cot set up had a cot pillow in there. Now i know cot bumpers are supposed to be bad, i've never used them, but what's with cot pillows? i never gave pillows to my kids until they were around 2 or 3, they say that they don't really need them till then...just curious...
