Try to find a local sling meet because you'll want to try different things out.
Some people like ring slings (I do to feed in) others can feed in wraps. Others prefer pouches because there is no adjusting to do. It also depends on your boob shape/size as to what will be most comfortable for you.
Whatever you pick will probably take some practice, but if you can find a sling meet there should be someone who has done it before and can advise you.
close carrier good for this - 2 stretchy ring slings so spreads weight well across back/shoulders and has good adjustment for bf positioning. have used a million slings, close was only one i mastered bf on the move with.
