Can I throw in another option? (not neccesarily instead of, but in addition to)
I have an Ergo Baby Carrier – best $100 I’ve spent. I wear my baby all the time. It can go back, front or side. My second was the kind of kid that didn’t want to be put down and the ergo was a lifesaver. I wore my older son when I was 9 months pregnant (on my back). I am still wearing my 17 month old and I am currently 6 months pregnant. Its also more convenient for grocery shopping, subway travel, shul and most other excursions.
