I use a few different carriers but for the newborn stage, I used a Kangaroo Korner Adjustable Pouch with both of my children. I loved it – it was lightweight, easy to use, suitable for a small frame. Mine were mesh so they were stretchy and breathable – great for my summer babies! I was stopped everywhere I went by moms and moms-to-be eager to know what I was wearing! Unfortunately, I think the company is now out of business.

I love this kind of baby carrier. It looks comfortable and easy to do.
