A Mom’s Perspective

When my twins, Emma and Ethan, turned 13, they weren’t short—but I still felt they weren’t reaching their full height potential. My husband is 6'0 (183 cm), and I’m 5'4.5 (164 cm). Based on that, Emma should be around 5'7 (167 cm) and Ethan 5'11 (180 cm) when fully grown.

But last winter, Ethan had only grown about 2 inches in over a year, and was 5'4 (163 cm) with a bone age of 13. He was around the 70th percentile for height, but based on genetics, he should’ve been closer to the 90th. Some of the boys in his class already hit 5'7" (170 cm). Emma, at 5'3 (161 cm), wasn’t lagging either—but her growth had clearly slowed. She’s already started her period, so I’m concerned she might not reach her full height potential. 

I didn’t want to just sit there refreshing the growth chart every few weeks and hoping magic would happen. When a doctor casually mentioned iKids-Growth, I didn’t jump in right away—but I was curious enough to look into it. There were mixed reviews online, which is pretty normal for any product these days. I figured we could afford to try it for a few months and see, so we started in December.

Honestly, I wasn’t expecting much—winter isn’t peak growth season. But after the first month, Emma grew nearly half an inch. After three months, she’d grown to 5'5 (163.8 cm), gaining 2.8 cm, and moved up 8.7 percentile points in her height ranking. Ethan grew a full 1.6 inches (4 cm) to reach 5'6 (167 cm), also improving nearly 10 percentile points. 

That’s when I knew I’d made the right call. I wouldn’t say iKids-Growth is a miracle—it worked alongside the basics. My kids eat well, get plenty of exercise—Emma runs cross-country and swims, while Ethan plays basketball and swims every week—and we try (though don’t always succeed!) to make sure they get enough sleep. But iKids-Growth did give them the extra edge at a time when natural growth alone wasn’t enough.

If you’re thinking about whether to step in—my advice is to look at genetics, look at the recent growth rate, and trust your gut. If there’s still room to grow, it’s worth helping them make the most of it.
