My Dh will wear Jack in public on a sling. We are getting a Bjorn mainly for him.. but he also wants to wear the zolo we are about to order. We tried a zolo and he ended up trying it for longer than I did and got DS to fall asleep in it. He was wearing Jack in a Corner Bakery with a Toile Zolo. We will probably get the natural one but he woudl even use the Toile if I would want that one.
I think he would wear DS in just about anything because he wants to do EVERYTHING I do with DS except for breastfeeding ;) He is an awesome daddy!
