Having outgrown both his peanut sling and Pippalily sling, Baby H needed an upgrade. I did some research online and found the WOMbaby sling. The adjustable rings make it easy to use - I was slinging away as soon as we made our purchase. The all cotton fabric makes the sling a cinch to wash - throw in machine and dont think about it. Getting Baby H (who is a whopping 20 lbs at 5.5 months) into and out of the sling is easy too - having the adjustable rings makes it much easier as opposed to an encircled piece of fabric like our older slings.
