I gave my one month daughter Gerber nursery water was I supposed too

If you mixed it with formula yes. By itself no

okay thank you very much why can't they drink it without the formula

Because you can over hydrate a baby and they could die. They need nutrients from formula. You don't want them getting full on just water

@bonniesue, I got it your absolutely right what age can she have water

When you introduce foods at 6 months you can give a little water with their meals

They say not to give plain water because their kidneys can't process it yet, developmentally.

@motherlotus, thank you
