I have carried my 4 year old on my back in the Ergo...we were walking around at night in Sydney and she was too zonked to walk herself. Was either that or carry my 4 year old and put the 2 year old in the Ergo. Best solution was 4 year old on back (not too bad in the end, lol) and hold 2 year old in my arms. Lol - did that all make sense?
