Breast fed babies

Are you giving your breastfed babies water? My daughter has maybe 1oz of water a day if that. She's strictly all breast milk fed for her liquid still. She doesn't nurse, just has pumped milk and is exclusively fed only breast milk as her milk. I'm curious when other breastfeeding moms start to give their babies water and how much. I've read that water isn't really necessary for breast fed babies especially and shouldn't even be given to babies and young toddlers. Her pediatrician hasn't mentioned liquids yet.
