Aren't you breastfeeding? If totally top fed,use any formula,all are more or less the same. Soya milk products are used for lactose intolerance,leading to loose motions. Do NOT,repeat NOT use cow milk,ever! For reflux,meds are rarely indicated. Try this: Gap between feedings at least 2-1/2 hours,NOT lesser. Burping for atleast 10 mins after every feed. Lay baby oh his right side for 30 mins after burping. Use a small firm cushion so that your baby is raised about 15 degrees,i.e,place it below head AND shoulders.
