I'm on my phone too.
The headrest looks high? I I think it was on the lowest setting in that picture. I wasn't paying attention to that, and had forgotten until later that it was adjustable. The shoulder straps are on the lower section, and not on her in that picture. The current setting is below her shoulders, but IDK how far down. I was just playing to see how she liked it, and to get a general idea of how it works, and stuff.
I'm happy to have a seat when needed. Also, I am glad that you gave me that push to get a better seat that will last longer!!
