You can buy goats milk and even rice milk at whole foods. They even have goats milk yoghurts. For when she is older they have a great variety of non dairy foods and snacks. My son has a Lactose Intolerance and still spat up after each feed we added rice cereal to his milk and it wasn't as bad. Because he did bring back all the time the doctor felt that he had reflux disease so took Zantac, this protects the lining of the oesophagus. The ear infections could be a result of her allergies/sensitivities. I wouldn't go down the tubes route yet, some babies are more prone to infections because there tubes are smaller and will improve as they grow. If she has a tendency to be congested, that can be another sign of allergies and even reflux, if you are not doing it already run a humidifier in her room all the time and even put saline drops in her nose. I run one in my sons room and find this really works. I hope some of this helps.
