What is the best kind of sling to get? Hubby is going back to work on Tuesday so my month is up :( we did a trial run to see how I would do getting the stroller down the stairs and what not and lets just say it's too bulky and coming back would be too much so I need a good durable sling for everyday use and is super condo for baby
