Any SSC like an ergo. Manducca are supposed to be good. I love my pikkolo. The hug a bub was great when my babies were small but as you carry the whole weight in your shoulders it's not so comfy for a big baby and I wouldn't put my toddler in it. My ergo/pikkolo/SSC's however carry my 4, 3 and almost 1 year old regularly. :-) there is a baby wearing group on Facebook where they sell lots of second hand carriers. Often there are good bargains. Baby wearing buy swap and sell I think it's called.
