Oh I exclusively babywear as in I do not own a buggy and I wear my 17 month old AND my three month old and can clarify it is not uncomfortable. I use ergo on my back for toddler and ellaroo wrap on front for baby. I even carried toddler on back in ergo until I was about 32 weeks pg, I love it.
However I did have to play around and find the right sling for me. At first I had an mei tai which I detested, I tried it when DD1 was a newborn and it felt unsafe, like her head was falling back all of the time/my neck was killing. So I tried a maya ring sling and I detested it.. I could never put it on right and it always killed like a bitch. I eventually got there with the ergo and haven't looked back since, love it! Definitely would advise an ergo..
Baby bjorns are the worst ones to use, along with bag slings (such as baba sling). The best slings are the woven wraps like the ellaroo and other companies do them too, or soft structured carriers like the ergo or beco. But it is personal, everyone has different opinions. But yeah, def avoid baby bjorns.
