My LO is 7 weeks old. As he is gaining some weight, the buckle in the carseat is getting too tight on his legs. It's tight enough that it will leave marks on his inner thighs. Does anyone else have this issue? Is there a way to adjust it so it doesn't leave marks? I've gone to the Britax website and watched the video but of course they use a doll instead of a real kiddo which doesn't help me to see how the buckle is supposed to sit. I had a friend look at our car seat and she said the clips that hook into the buckle in the car seat stick out way farther than their car seat and she didn't think that the buckle should be leaving marks on our LO (which I agree with, just can't figure out why it's doing that).
