Dairy alternative

My son will be 1 soon and I have breastfed him since birth and I want to stop after he turns 1. Now I know he can have cows milk but I don’t want to give him too much cows milk because I know it isn’t the best thing in the world but I don’t want to shelter him either. Just kind of want to give him a little bit substitute with something healthy too that has benefits also. What else could I give him?
