Should we get bothered about my very brilliant nephew's growth rate. He is very healthy, but it doesn't seem to me that his growth is optimal. He just turned 6 in September.
Parent are not too tall though, but maternal grandparents are. I don't know but I think even with the gene factor, he should be taller than he is.

MORE PROTEIN IN HIS DIET IS ALL.


E.g
In the morning, FULL CHICKEN
Afternoon, BEANS AND 3 EGGs
Night, Assorted meat

Drink more milk than water.

Rich parent. He has all that

Nairalanders create problems where nothing exists. If you want his full growth potential, adopt him. Leave his parents to do their jobs. You said his parents aren’t tall, what then are you expecting? Not everybody is meant to hit 5’8 and taller. Some people stop growing at 4’9.
