The problem with amazon.com shoe shopping for baby is determining what is the right size.  So I'd like to let you all know, that I purchased this shoe for my son, and assumed that 6-12 would fit him.  Well... it does but barely.  I believe these shoes will only last about a month, before becoming too small for his feet.

Age:  9 months 3 weeks

Size Purchased:  6-12

Weight of my baby:  17 lbs  (he's very long for his age) --- not a chunky baby

How does it fit?  Snug.  I should have purchased 12-18 months.  My son is almost a size 4 in infant/toddler sneakers.

I like the shoe, it is exactly what I expected; but, 6-12 months is really for a baby who is closer to 6 months rather than 10 months.  So if you have a 10-12 month old, I'd recommend purchasing 12-18 months for a kid this age, that is, unless you have a small child.
