Feeding questions

Hi mom's. I have a question. I was told that I could already give my baby water. My question is.. how do I balance it out? I give him a Gerber, followed by formula. When do I give him water? In between bottle feedings? Right now I'm giving him a bottle (8oz) in the morning. A Gerber and 5oz of formula for his second and third feedings and a bottle (8oz) at bedtime. Sometimes he'll ask for another bottle if he wakes up in the middle of the night. How many times a day am I supposed to give him water? I'm so afraid I'm doing this all wrong. Am I feeding him enough Gerber? Do I give him snacks in between so he'll start trying new foods? I was told I could give him eggs already, but he hates them completely. Idk what to do.
