The average weight gain for a one year boy is to triple their birth weight. Most children that are one year old have grown by 50 percent and have gained 9 to 11 inches since birth.

There are protien shakes that help you gain permanet weight if you are having trouble with this.
Anything unatural shouldn't be considered safe. You can give him "Gain powder" but i suggest you visit your MD before doing so.
