Question about baby sling?

I am pregnant with a baby due in September. I have a toddler who will be 16 months when this one will be born. I am looking for an affordable sling that you can nurse, carry while caring for the toddler, and easy to take with you as well as hands-free. (meaning I want to be able to use both of my hands while my newborn is in the sling). Any experienced mothers recommendations? It would really help. Thanks.
