Is this too much space?

We have a Graco 4ever convertible car seat and I took out the insert that came with this because she is a bit too tall and the headrest kept coming out.

But is this too much space between her body/head and the seat? She’s 9 months and tall but very small, probably not 20 lbs even.

Update:

This is with the insert. I think I still need to lower the main headrest. The shoulder straps are below her shoulders but the lap belt is still a bit high.
