N.O.
I used Enfamil Next Step with my son when he turned 1 and was very pleased using it. We ended up using it until he turned 2.
I thought it was great to have because at that age, they tend to become very picky eaters and it's just another way to ensure your baby is getting proper vitamins and nutrients until they really eat well.
I have also used Similac Advanced if the store was out of Next Step and also liked it very much. My son hated the Nestle Good Start for some reason but did very well with the Similac & Next Step.
Take Care!
