Yeah Lana,
I guess that's what I don't like it looks like her head is sometimes in front of it instead of in it. When I put her in there I nestle her head into it thinking it must be comfy, but on warm days i notice she's basically got a think hat/covering on her head, the darn carseat is already hot enough being made of polyester/plastic.
Her head does lean a bit forward when she falls asleep, and the head rest doesn't appear to be giving her a lot of support, but I bet I'll notice a difference when I take it out.
Ktkat,
How much does you 7.5 mo old weigh? I know holding their head up purely developmental, but Jules is also a larger baby in the 95 % for all her measurements...my friends baby who is 9 months old only weighs 3 lbs more.
