Other reviewers stated that these ran small, so I bought the newborn size hoping it would fit my 5lb son who was born a premie, but who is now stranded between "too small" premie clothes and "too big" newborn clothes.  Unfortunately, these are at least normal newborn size, if not a little big.  His feet barely reach past the crotch.  But construction and fabric quality seem good.  Thicker, not thin or cheap feeling.  I'm sure it will work great for us in another month or two.
