Gerber Unisex Baby 5 Pack Variety Onesie - Bears (Baby)

In general, Gerber brand runs small and is good for babies that are long and thin or if you have a preemie. The Gerber fabric is also slightly see-through so you can see the line on the diaper change from yellow to blue (shows when needs changed) without having to undress. We bought size newborn in the bear pattern. They fit our newborn baby the first three weeks (my baby's birth weight was 8lbs 1oz and lost weight then went back up again in weight to 9lbs).
