Nickelodeon legend Kel Mitchell of All That, Good Burger, Kenan & Kel and Game Shakers has just experienced a major life milestone. He and his wife Asia Lee just welcomed their first child together, a baby girl named Wisdom, into the world. Warning: Cuteness overload ahead.

Kel isn’t the only former Nick kid who has become a parent. Seeing how fast the children of the network have grown up is yet another constant reminder of how fast time flies. But what’s truly mind-blowing is the fact that many of them – including Jamie Lynn Spears and Nick Cannon – have grown up to become parents themselves!
