Pros: Easy to put on, Comfortable to Wear, Great Price
Cons: If the fit is right it can be tricky to get baby in and out as they grow, until they're ready for a new position
The Seven Sling was my first sling and while I "upgraded" to the Maya eventually this sling was great with my tiny newborn and made breastfeeding while babywearing simple and discreet.
Maybe because I am new to babywearing... I found the pouch style a bit more constricting as baby grew and moved to the Maya, Now that my LO is 7 months I may pull this one out again and try it in the hip hold position.
For any mom looking to *try* babywearing, this would be a good first step. It's inexpensive enough to "upgrade" if you decide you like it and i's durable enough to keep around for continued use.
