Alie Ward does the Ologies podcast, which definitely has inappropriate language for kids, BUT she has a kid-friendly series called Smologies.
Ologies → Smologies. It’s all of the science, with none of the swearing! Smologies are shortened, kid-friendly episodes of the award-winning science podcast, Ologies, which covers topics from Toads (Bufology) to the Moon (Selenology) and everything in between. Enjoy clean and witty bite-sized science delights as host Alie Ward asks Ologists of all kinds smart – and sometimes silly – questions. Get to know the charming and diverse array of experts who share not only their wisdom, but also their lived experiences.
My kid is only two right now, but I hope if I suggest this now, maybe there will be a card by the time she's ready to listen!
