I bought this because my big 16kg toddler doesn’t want to be in the stroller but doesn’t want to walk much either. This sling can hold my big toddler good and sturdy and give me less pain in my arms. The split shoulder design avoid the strap digging in to my shoulder or neck, so it gives me less stiff shoulder than other products. The anti slip design is good as well. Since I bought this, I’m more confident to take him out without stroller and now he can walk 1km himself who didn’t even want to walk 100m before the purchase. Thank you!
