Any mummies using NAN Optipro HA 1? Is it good?

We are using it since birth, for almost 6 months. So far no issues with it.

My child intake the nan but not ha 1. Yellow one I think is for allergy?

I did. It was ok but my child prefers other brand. So far so good

Yes its good My LO tried both NAN 1 with and without HA.

thanks
