Thanks for the advice. I have been looking around at different carriers and i like the look of the slings the best but im not sure if they would hurt my back and shoulders too much. I have been looking at the ergo which i like, can you use it to carry bubs on your hip?? i know with that one you cant face out but the hip carrier might work instead. DS tends to throw his weight back at the moment too when sitting on your hip so im worried that he would fall out of a hip carrier, would a sling or ergo be better for this?Does anyone know approx how much the ergo is?? How long did people use their ergo and what weight do they go up to? Has anyone with back problems used a sling and which one? Sorry for all the questions but there is so much choice out there and i want to make the right decision as this will be our second sling and DH wont appreciate me wanting to get a third ha ha!
