Nice bottles but LEAKS ALL THE TIME

I like everything about the munchkin bottles except that they just leak all the time! I’m constantly having to mess with the blue valve on the bottom so that it doesn’t leak. I literally have a poking tool next to his bottles because I have to poke at it to stop the leaks every day! So annoying!! But I am stuck with 7 bottles and don’t want to spend more money on new bottles.
