Pretty much every time I go grocery shopping with all three of my little people someone makes a comment. They either think I'm crazy, brave, amazing - something to that effect. When they comment about it or ask how can I do that (besides the fact that I HAVE to sometimes!) I just say, "It's because I have a sling." I know people think it looks like hard work because I'm carrying him but it's SO easy, both of my hands are free to catch the other two!
To Pamelamama, I love carrying my baby on my back in my sling too. Even if I'm just working around the house, it feels so natural and it's so nice to have him close. Besides the fact that he loves to rip my hair out when he's back there, back wearing is always a proud sling moment for me too!
