They fit my 6 week old perfectly.
These worked perfectly for my 6 week old son. We used them during a marching band parade (24 bands with very long percussion strings) and he slept the entire time. My husband also brought him up on stage during a concert and he wasn't the least bit upset about the noise. They're very light weight too. He doesn't mind wearing them for long periods.
