My daughter is 3 weeks old. She had an appointment and has only gained .1 oz since birth and I've been breastfeeding. So the doctor wants me to nurse on both sides then pump after feeding and offer her a bottle of formula or breastmilk ( I don't have any milk yet saved) how can I make my supply higher. Also she will not take the formula bottle i have similac soy mainly because everyone in my family has a dairy issue. How can I get her okay with the formula?
