I'm trying to decide what size spibelt to get for Charlotte. Her waist measured 22 1/2 inches. She's 4 1/2 and about 44 pounds. The kids' belt says it fits 14 to 23 inches. I can't imagine she needs an adult size, but I also hate for this kid size to be too small. For those of you that have spibelts, do you think she'll be okay with the kids' size?
Get the kids size. My 5 1/2 year old son weighs about 43 lbs. Not sure of his waist size, but I'm thinking it's about 22 inches. The spi belts are adjustable and he wears his on the smallest size! My 92lb 10 year old son can still wear the kid sized spi belt pulled out to the largest size.
Get the kid size. My almost 13 year old daughter wears the kid's spibelt--she is petite. You want it so it doesn't flop around.
