I agree with bbpooh, you look so young bor!!
Well, even my yan yan say that their sling is worse than our sling, she complains shoulder pain as well, so I gave the purple one (friends bought me as a gift abut I already bought one) to her for carrying sum sum, actually don't wanna share a sling with her...
I am not as lucky as you la, my 99 is very stubborn and she wants to 爭湊 sum sum ah, very 煩, dunno how to deal with her...
