TWO QUESTIONS!

Nope and nope Not until 6 months

My son got dehydrated and doctor was shocked I didn't give him water! And says to other him water throughout the day he drinks like 3 oz

since my baby’s 4 month appt doctor said i can start giving him water. so i give him water about 1 to 2oz a day. & he was diagnosed with reflux around 3 weeks old since then ive been giving him oatmeal cereal, doctor said a teaspoon per oz.. but now im giving him less cereal since ive started him on solids.
