Most of the ones i've been looking at are age 2-3 (12kgs to 16kgs) then the next size is age 4-5 (17kgs to 21kgs). Ds is 2.2 and weighs 15kgs. What size should i get? They're not cheap so don't want to waste money.
I'm looking at the Konfidence ones, has anyone got one and are they good or would you go for cheaper ones?
