These sleepers are nice, warm & cozy.  The material does ball up a bit after several washes, but not so much that I wouldn't buy it again.

My main issue was with sizing.  I just looked at the ages & since the choices were 6 months, or 12 months I assumed my 5 month old would easily fit into the 6 month size.  It does fit him, but he won't be able to wear them for very long.  I would lean towards the larger size next time.
