5. Youth - 12/24 M

Ordered the 12/24 month size and it fits my 15-month-old with a little room to grow, which is exactly what I wanted. He wore it all afternoon without any fussing or tugging at it. Nice to have a size that actually matches the range on the label.

My 14-month-old is on the move nonstop and these actually stay put through all the crawling and climbing. The 12/24 size has just enough room to grow into without looking baggy. Ended up ordering more the same week.

My niece wears this in the 12/24 months size and the fit leaves plenty of room for her cloth diaper, so it hasn't felt tight even as she's hit growth spurts. She can crawl and pull up without any restriction, which is exactly what I wanted for this stage.
