I believe this kind of "baby hair" is something people naturally have, so it's a genetic trait. However, there are some things you can try. Hair loss shampoo, like Formula 500, is meant for people whose hair is thinning and hairline is receding, so if you make sure to get the product on your baby hair it could be helpful. You can also apply hair loss treatments like Rogaine for Women (or something else with the active ingredient Minoxidil) on the areas where you would like more baby hairs. I hope this helps!
You can't really "make" them. If your parents had them, you probably will too. Can I ask why you want them?
