I found that there are several excellent baby y carriers out there. I've settled on prefering a carrier that goes over both shoulders and allows you to carry baby on front and back, as well as a sling type carrier which goes over one shoulder and is easier for nursing. I use a podegi (similar to a mei tai) and a hot slings carrier. I love them both for different reasons. The sling is good for quicker trips. The podegi is great for long carrying and is comfortable for longer since it goes over both shoulders.
Those are the ones I've tried, but I imagine there are plenty of great ones! Also I do prefer foam padding in the straps of the podegi, so maybe find something with thick padding, like on a backpack straps. With the sling, I prefer no padding.
Good luck!
