I am 16/17 weeks pregnant with a 6 year old special needs son (relevant because he could not walk until a year ago and is only now independently walking.) I actually have a question at the end of the post between the Boba 3G and the ERGO
From 0 to 3 months: Over the Shoulder Baby Holder Ring Sling: When ESP was newborn/infant, he was a winter baby. We loved the OTSBH, the extra padding all around the edge was more comfortable for both of us. Nursing was a bit tricky because I have very large breasts. I actually got a wedge meant to go under the breast to give it some support for feeding! At first we had an Infantino sling, but E got over heated in it - later it was recalled for just that reason. I learned not to buy slings from companies that were just jumping on the babywearing bandwagon, but stick to companies that had been doing them long term.
From 3 to 12 months: We used the HotSlings SolarVeil material sling. The material has a texture but is not scratchy. It is very breathable and we could use it comfortably even in the summer. Took summer trips easily with this sling. I actually still have this one! and am excited to get to use it again. The new baby is due in Feb, 2013.
Ergo with the Infant insert (the 2007 design which is different from the 2013 design). Both of us LOVED this carrier. Too hot during the summer but awesome once the weather cooled.
My husband like the Baby Bjorn but I always had to help him get into it. Was not my favorite because the position of the baby's legs did not seem natural. Also got hot as we moved into Spring and Summer
From 12 months and older:
ERGO: This was a fantastic carrier. I had to stop using it when ESP got taller because he did not have neck/head control. I was never able to wear him on my back which I think would have been a very freeing option for me.
This time I may try a Boba 3G, I have heard it comes up higher on the baby's bac/neck than the ERGO. Does anyone have confirmation of that???? Hopefully, this new baby boy will not have special needs but if he does, I may need the highest back option.
