Family history of formula allergy

Has anyone dealt with family history of formula allergy that it ended up that your baby was allergic to it? We have an appointment with the pediatrician soon which we will discuss this.

My husband and my brother in law was allergic to it and my brother in law had a baby that was allergic to it as well.

My baby is due in March and my husband is freaking out that our baby may be allergic to formula due to family history even tho I plan on breastfeeding. I successfully breastfed my daughter 12 years ago so I'm not worried but this is my husband's first child so he's a worrier.
