HAB was too complicated for me. Am sure it's great but it was taking longer to get on than getting where I wanted to go plus I think it's a rip-off for a bit of jersey cotton. So I got the Baby Bjorn which is also expensive (but I can see that there would be some manufacturing costs in there with all the clippy things) and is a breeze to get on. Am not mad about it but it's main advantage for me is it takes two seconds to get on and I have the peace of mind of knowing that
DD is very secure and is not going to slip out.
