For the first few weeks I used something very similar to the picture shown. Unfortunately, I do not have any photos of Sarah in the sling. However, when she was very small, it was great way of me carrying her on my lap when I went out.
As you can imagine, you place the sling on your lap, lift baby inside and then put the strap over your head - dead easy and peace of mind that baby is secure.
I didn't use it for very long as Sarah didn't like being enclosed in this way after about 6 weeks. It was then that I moved on to the baby carrier.
