My 1 month old is currently on enfamil but it does not seem to agree with her so we want to change her to aptamil. When changing can i just give her the new formula or do i have to introduce it gradualy.
We shifted from Friso to Nan HA when baby was around 3 months. We just gave him the new formula when we finished the last can of Friso. He didn't seem to have a preference and took the new one just the same.
