The new Aptamil Gold because its has prebiotics and immune boosting ingredients like HMO

You can consult your doctor before starting formula your baby, Aptamil is prebiotics formula milk, which closer to mother milk.

Try feeding all and then see how your baby is reacting to different formulas.

Since I have used Aptamil formula personally I can say that it is the closest substitute to breastmilk it has DHA and pre-biotics which is great for the gut health of the baby

Can’t say about others coz my daughter & niece have been on Aptamil and it worked well for them.
