I recently brought light weight stroller for my 15kg girl.its apruva lightweight folding stroller from Manila Philippines
I used yoya(yoyo replica) When my 18kg son sits in it, it still can move! so can consider. Or a mclaren umbrella stroller
15kg no problem. you try gg to fair ask ur 15kg toddler to sit on it and try pushing around to have a feel
I would get a used YoYo.
