I used it last night for our walk! I walked Hallie until she slowed down and then put her in it. It was really really comfortable for me! Hallie actually fell asleep before we got home
I hooked her in to the strap and had both hands free for Simon. It is perfect size for her (she's 6 pounds) and she loved it!
I should also mention that Simon doesn't fit in it (he's a lot longer than Hallie). Not that he would ever be caught being carried anywhere
haha
