My dd is 6m and is on elecare for dairy allergy (also has soy allergy). We started solids. Now shes got that acid smell Im pretty sure its acid reflex. Could they develope from solids?

She was doing great on elecare before. I been giving her earths best cereals and their vegs, and fruits.

Probable a stupid question but Im curious.. could Earths Best Sweet Potatos have dairy in them? Seems like she started after having those. She hasnt had since the 21st.
