Hair loss

Rebecca

We switched our babies formula about a week and a half ago to help with spit up. We are now using Emfamil AR. Also within the week of using it, we’ve noticed our baby has lost a significant amount of hair on the left side of his head. I’m aware that babies lose hair, but now I’m wondering if the changing in formula could have any affect on his hair loss. He is 4 months old. Thoughts?
