That's an interesting calculatorm but I'm not sure how accurate that really is. It didn't really work for my family, anyway. My mom is 5' 4" and my dad is 6' 1".
The girls in the family according to the calculation would be 5 ft 5.5 inches, and the boys would be 5 feet' 11.5 inches.
Sis One: 5'8
Sis Two: 5'4
Still, you can at least get an idea based on parental height. Obviously in my family we had a shorter mom and a taller dad. But in my mom's family some of her siblings are quite tall and some are mom's height. Likewise, my dad's sister is my same height, 5'4, while he is tall. So we ended up with a couple short girls, a really tall girl, and a short son. A big range of heights, but none of it was surprising as it was all within our genetic range. Had one of us girls been 5' or 5'2 it would have been unusual, or if my brother had been 6'5 or something like that.
So how tall are you, and how tall is your husband? How about your parents and his? Siblings? Unless everyone in your family is tall I wouldn't worry about the drop off necessarily.
Beyond providing good nutrition for your child I don't believe there are any foods that can make them taller.
Giving them a very poor, nutrient-devoid diet could reasonably stunt a child's growth and development, though. That is not much of a problem for most of us, thankfully. (though it is for far too many people in the world).
Also, if a child had a strong allergy or intolerance, or an autoimmune disease like Chrons or Celiac it could prevent them from absorbing the nutrients they need, and therefor inhibit growth.
