Powdered Formula

Tracy
So I went out and bought powdered similac w/HMO (photo shown is exactly what we bought) and was wondering what some of you mamas used for water. Baby girl is 3 weeks old and had been fed the ready to feed which was getting irritating waiting for bottle to warm while she screamed. I also pump
Breast milk after breakfast lunch and dinner which gives me about 3 bottles and I feed her those as well...... what I did was I boiled tap water, let it cool 30 min than poured 4oz of water into my sterilized bottles.
