Which is older an infant or a baby?

Is one a sub group of the other? Does either term include toddlers?

I'm having this discussion with someone and we both thought the opposite from eachother and we were quite sure our way of thinking was the common understanding.

  • i don’t know the specifics, but i feel they’re just synonyms and they share the same age range they’d represent. in terms of subgroup, id say infant is a subgroup of child based on what i hear and say. Like i wouldn’t say i have an infant baby id just say baby. Or i don’t have a baby child, i have an infant child. 🤷‍♂️

  • There's not a specific difference in most cases. But generally infant can be used outside of humans whereas baby is specifically a human child. And in some professional and scientific jargon infant is used to describe a specific phase of life.
