We have one of those, but haven't used it much yet. In Disney we used the Baby Bjorn when my daughter was 3, 4, 6, and 9 months, but I'm thinking I'll be using that carrier more on our April trip when she'll be almost 14 months. We actually have the Playtex version (Hip Hammock) and we got it at Babies R Us. It's comfortable to wear and my daughter seemed to like it enough when we have used it, but she seemed a bit small to me for it. It looked like she could fall through the leg openings at the time (she was 10 months, 28.5 inches, and 18lbs 3oz). She's a bit bigger now so I'm hoping she fits in it better (though not much, 29.25 inches and 18 lbs. 12 oz.), but she's a bit on the thin side for 11 months (25th percentile in weight) so I'm not sure how your child would be. The weight limit starts at 15 lbs. and goes up to 35lbs I think, so I mean she technically fits, but I feel the Bjorn is snugger for her=less scary for me. Even so, we'll be taking it with us to Disney in April. Assuming she's walking by then, I might also bring a harness for her so that if she doesnt' want to be in the stroller we have another option. My husband hates harnesses on babies, but I think it might be worth it not to lose her.
