THE CROTCH BUCKLE IS SO HARD TO UNBUCKLE! I HAVE TWO OF THESE SEATS AND THEY ARE BOTH THE SAME!! I SERIOUSLY HURT MY THUMB TRYING TO PUSH THE BUTTON TO RELEASE THE BUCKLE... I THOUGHT IT WAS JUST ME UNTIL I DID SOME RESEARCH! THIS IS RIDICULOUS! I PRAISE THESE SEATS TO EVERYONE, MY ONLY COMPLAINT IS THAT IT IS SO VERY HARD TO RELEASE THE BUCKLE... IS IT SOMETHING THAT CAN BE REPLACED? I HAVE AT LEAST 2 MORE YEARS OF THIS!! *TR
