Appropriate recline for a 5 month old in Roundabout?

[wolverine2]

We just moved my almost 5-month old from the Snugride to our Roundabout (outgrew the old snugride by weight)! He keeps lifting his head up in the Roundabout- I guess to see what's going on(?) and I'm wondering if it's ok to recline it a bit less? It's not super-reclined now, but he's doing some serious head-lifting and I'd rather he just took it easy!

Heh, funny, look at the caption on this picture http://picasaweb.google.com/joolstag/LeahInCarseats/photo#4968704647613317138

I think her head flopped to the side a bit when she slept, but I wasn't worried about it flopping forward and cutting off her airway... does this look more upright than yours?

Very cute! I think it might be a little more upright than ours. The only way I can think of to get it more upright would be to change the recline with the bar... if the tether was loosened any more it would be slack. Is it ok to make it more upright? His head isn't flopping forward at all now- he's straining it forward.
