Thank you so much for reading the IPC blog. And what a great question?! Baking soda can be toxic to toddlers who eat too much of it; the sodium load overwhelms them. If they are soaking in a dilute solution, they should be ok, as the salt is not absorbed through the skin.

Think of it like the salt in the ocean. If you swim in it, you are ok, but if one drinks nothing but salty sea water, it can be dangerous.

Thanks and please keep reading!
