I had ergo before DS1 was born but didnt like it with the infant insert, it is awesome after about 4 months when they have better head control, I t can be used on front, back hip. I can carry DS1 who is nearly 3 in it for long periods, last year I walked down to the nobbies at phillip island with him on my back with no discomfort.

Close carrier gets bubba very snuggled and secure against you.
