My 4mo is a big guy (16 lbs and 27 in long), although he's not quite tall enough to see over the straps. In fact, his eyes/nose are right at the top, which totally blocks his view of anything. He gets pretty aggravated that he can't see anything, especially since he's used to my RS that allows him to flirt with everyone.
Is there anything I can do to get him higher? Maybe put a small folded blanket under his bum? I don't want to do anything safe, but he's getting a little heavy for long treks in the RS. Thanks!

Re: Quick Ergo question
Do you have the Heart 2 Heart infant insert? If so, you can pull the pillow out of the bottom and use it to elevate LO. That's what I do and DS loves it.

I did the same thing! Worked great and worth it. You could use a blanket as well I'm sure, but the pillow insert you don't have to worry about refolding it or anything : )
