I have a tall two-year-old who isn't keen on her buggy, but does get tired sometimes if we're out without a buggy despite being a strong walker (we walk/get public transport most of the time). She's about 2 stone/28 pounds.
Both of these carriers look good as a backup option. I am swayed by the Boba - it looks like a nice, simple, streamlined option - but wonder if the Scootababy might be a better option since dd will want to be up and down a lot and the hip carry looks handier than a back carrier (I won't generally have help getting her into a carrier). Is the Scootababy OK for your back with a bigger child, though?
Does anyone have experience of either of these, or similar, with a child of this size?
