I don't have kids (yet). But if they will ever get into swimming and it comes down to this discussion, I learned this from my parents (when I was that little kid and begged for my first tech suit):
as soon as they qualify for nationals, I will get them their first suit.
Overall, you don't need a tech suit to swim fast. It's all mentally IMO.
I still have tech suits from 10 years ago and still swim in them (yes, they are still legal). I use them maybe 2x a year for taper meets.
