I too want to know about sizes -- please answer the question about a kid of 3 1/2 years old -- what size would fit her?

I checked Speedo's website and this is what it says: SIZING: S/M - Ages 0 to 18 Months M/L - Ages 19 Months to 3 Years

Hi Kristine, I am not sure of the answer. I used the size chart online and it matched well with my granddaughter's size at the time (since much bigger) and my own. Sorry, that is the best I can do.

It fits my 2 year old daughter. She will be 3 next month. Has enough room for her to grown into a little bit as well. See it lasting until she is 4 at least. She loves it.

My daughter will be 3 in August and they for her great. She's in the 60% for height to give you an idea of height. They extend from upper chest to mid-calf and tie very nicely. Def lots of room there.

My girl is 2 years old and it fits her good! I think between 2 and 3 is fine!

Since your child is almost four I would recommend the 4-6 size for her to room to grow in but overall you should go with the size based on her height rather then weight at this age. if she is smaller then average a 3-4 should fit fine but if average to taller the 4-6 would be better.

It will fit! I bought it for my daughter who was 18 months at the time. Now she's 2 and 1/2 and it still fits.

I would say "yes" if your child is petite. My little girl is 2 and I bought a 3T and fit her perfectly. But she is chubby in the thighs and tall. You could also check the size chart to see what is says too. But I would get the next size up for room kids are pretty active. My daughter wears hers all the time.

It seems logical to get the medium so she can grow into them based on this sizing info online. Size Shoe Size Approx. Inches Small Toddler 7 - Little Kid 11 5.5" - 6.75" Medium Little Kid 11 - Little Kid 2 6.75" - 8.13"

I purchased this as a gift for a 3yr old, who is tall for her age. I know they would be big on my 2yr old, who also is tall for her age. It is, I believe, recommended for sizes 4-6. You'd have to judge by your granddaughter's size. If I remember correctly it's all elastic waists. You could alter them if you're quick with a sewing machine but not sure it's worth it. It also contains quite a few small items/accessories I would not want my 2yr old using, although you could just withhold them. Good luck finding something for this age group. I've been looking and it's very difficult. There definitely is a gap in the market. I purchased this as a gift for a 3yr old, who is tall for her age.

My daughter wears a 13-1. I got her the 1-3 size, and they fit great. Hope this helps.

My daughter is also 3 and wears about size 8. They are very big on her. I would say maybe a 12... She still loves to wear them though!

My daughter is a big 16 month old, 26 lbs and 32 inches. My guess is that a 3 year old would probably fit well, but again that is just a guess.

Depends on how big she is. Probably XS or S. Got an XS for my slightly taller than average but slim 5 year old and she will probably be able to wear a couple years as it is long on her. You can look at size chart on UA website.

I am using size 4 for my 13 month old. 4 is deff fast. 3 is medium. I believe size 2 is the slow one.
