ELI5: Why dont we give babies water?

I dont have kids, I'm just curious. And this may seem silly but I've never heard this being asked and I was just confused, we as humans need water, as it makes up 70-ish% of us... what about babies though?

Newborns being breast fed only need mom. It’s a system with feedback that works very well.

Later on, babies are given boiled water to cook and annihilate microorganisms which are dangerous to them.

And much later we give them beer because every human has a right to enjoy the accumulated knowledge of their ancestors hard work.
