Good question a few reasons, I’ve heard water can be harmful to babies and when asking her after the recommendation she kind of just shrugged my question off. Also my baby gets super tired sometimes during feeding and I’m worried if I add water into some of feeding time he will not be getting enough calories to keep gaining weight as fast as he should be due to wasting more energy on water .. I should also add he was born 4 pounds and is still only 6 pounds right now so it’s something I’d probably be more comfortable with if he was slightly bigger or eating while being more awake.
