Keep in mind the worst thing you can do to a kid is to tell him things that may make him self conscious. So hope you,( and grandparents as well- they are notorious for making bad statements), don't say anything to him like "I am sure you will get taller" or anything like that. Really causes a lot of stress on kids if they perceive they should be taller, skinnier, better looking, smarter or whatever.
Most kids are near the height of their parent of the same sex, within usually a couple of inches. If the male parent is shorter than his own father, certainly a good chance the kid could be somewhere in between. But also keep in mind that genes for height can come from the mother's side, and go back a couple of generations.
So your son could inherit his maternal great grandfather's height. But it could be quite tall. Just a big crap shoot guessing anyone's height since in modern times ancestry for kids due to mobility can be from various regions.
My own son is 4 inches tall than I am and in the top 1% of all males in height. I am only in the top 15%. My mother was less than 5 ft tall, dad was a couple inches shorter than me.
But my grandmother was as tall as my dad so betting that is where my son got his height genes. Growth can be in very obvious spurts, or just slow and steady. My son grew 6 inches in one short time span, my brother-in-law grew nearly a foot over his 18th summer.
I never had a growth spurt, just grew steadily until 15 and am above average height. Most guys I grew up with generally did the same. So your son may have had an initial spurt, but could finish out over the next few years gaining an inch or two a year.
Just measure him every six months and see how he is doing. But please NEVER let him know YOU want him to be tall. He has no control over his physical growth, neither do you, so there is no way he can achieve YOUR desire by anything he has any control over.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
