Hello,
I have a Be Cool Outback stroller, I use it with the crib for the little baby (1 month), every time I go down the stairs with the stroller after a step or two the stroller folds even though I make sure to hear the click when I open the stroller after folding, it's really scary and dangerous, I looked in the brochure the instructions and I didn't see how to lock the stroller so it won't fold, do you know please tell me how to do it?
