Enfamil Aplus Premium

Hello everyone, we have been using Enfamil A+ premium as this is the one they gave us at the hospital, my son is almost 3 months and has been taking this one, they have now discontinued this type and a new formula is replacing this one "sometime in the spring" according to the contact I spoke with at Enfamil. When I asked what is a good replacement that is similar, they said to ask my doctor 🤦🏽‍♀️ Is anyone else using Enfamil A+ Premium and if so what are you using to replace it ?
