Do you believe in "hamog"? I personally don't, but my parents always nag at me whenever I take my son out at night without any headdress (bonnet or hats). Is it another old wives' tale that has been cemented in our culture for centuries?

I think there's some truth to this! But it's mostly because if the temp gets super low at night, naturally, babies can catch a cold. This is because of mist or fog. However, I don't think this applies to warm nights. Either way, it's better to be safe than sorry!
