Which Gymnic Hop Ball do I get??

[Tammy]

Confused on sizes for DD1 who is 6 yrs old and approx 44-45" tall. The Gymnic Hop Ball 55 (22" dia) says for 6 and over. The Hop Ball 45 (18" dia) says for 3-5. But when I read reviews I see some that say the 22 is too big for the older kids and the 18 is good for their 5 yr old. I don't know which one to order and this is for her Santa gift for Christmas morning so it will be inflated and ready to go! Anyone have experience with either of these or recs? Thanks!

I got the 22" for dd last year when she was 5 and it was (and still is) a good size for her. I'm not sure how tall she was then, but she's pretty average for height.

Great, thanks! I'll try this size then.
