I had a bubba moe, I hated it, I sold it as DD hated it too. Found it really big for her and she kind of got lost in there and really didnt like it.

I think the peanut sheels are a bit smaller and might be better.

We actually really like the baby bjorn. I find it really comfy and she has loved being uprigh from about 4weeks old so it works for us.

Maybe you can take her to babies galore and try DD in their slings and see what works for you girls.
