Babies can drink water – like its a thing that could happen. The main issue tends to be that babies have teeny tiny stomachs and teeny tiny kidneys and comparatively high nutritional needs.

If they drink a lot of water at once, their kidneys might not be able to process it quickly enough or efficiently enough.
