I measure the bootie sole from the center of the heel to the
center of the toe. Size small is approximately 4 1/8" long, fits about 0-6
mos.; size medium is approximately 4 5/8" long, fits about 7-12 mos.; size
large is approximately 5 1/2" long, fits about 12-16 mos. The ages are just
a rough guide since babies can vary so much...that's why I actually
measured the booties so if you use a ruler on the baby's foot you can know
which size to go with.
WBBB are as easy to care for as they are to use.
