Hi M..
First of all, Congrats!!! Exciting and wonderful. I have a 7 month old and when expecting had similar issues on slings. Some looked cool, others sorta comfy others difficult to deal with because they even came with a DVD! Because of the recall issues with certain items (even carried by Baby's R Us, my husband and I went on Consumer Report and made an educated decision for the Bjorn. It ranked high especially with safety and is quite comfortable. My baby was born 5.2 lbs and I have been using it ever since. At home, walking around, traveling and I even breast fed with it.....it's very private. If you do wish to go with another type of sling, investigate it's quality and safety and some mothers found it better to wait until the baby was born to try out different styles. Many babies feel uncomfortable in them and so can you (once the baby is in). No hurries is my advice and educate yourself. Enjoy!!
