My little boy hates food, as a result, he still looks like 2+ years old boy although he is almost 4. The doctor advised us to feed him an egg everyday so that he could get the balance nutrients for maintaining his body health. But, he hates egg since he was a baby. That's why, i wonder can i feed protein supplements to my boy? According to some of my friends, supplement foods are better for kids over 6 years old. Or, do you know where i can find protein related foods to my young boy? He definitely needs to grow his body.
