(IF that makes sense!)
Have ordered an Ergo to try but lots of people have said that their babies can't see over their shoulder. I have a Mei Tai and a woven wrap that I had for ds2 but have a neck injury and struggle now with high back carries, so I need something with more structure around the waist (also find woven wrap too fiddly to use when getting out of the car - ends trailing in puddles etc) Ds3 is 4months and very long so gets in the way a bit on my front.
Was looking at the Beco but can't see that the seat would be any higher on the back. Am I just stuck with this until he gets bigger?
