No pee overnight

My baby has his milk bottles and pees through the night. He has diaper change every three hours. So it’s not common for baby not to pee unless she’s not drinking milk at night or probably dehydrated. Is the water proportion correct to the formula?

Wow..is she bottle-fed or latch? She doesn't need night feeds anymore?

its common for a 3 years old but not a baby under one

no it’s not, probably slightly dehydrated
