Millionaire Matchmaker couple Rachel Federoff and Destin Pfaff got an early Christmas present Monday evening (December 20) when their 1-year-old son, Sin Halo, started walking! The proud mama took to Twitter to share her excitement!

Omg I’m crying Sin just took his first steps!!! Best day ever <3

We’re hoping this is a sign that Sin is feeling better after tweets earlier this week that he was under the weather: “Been up since 5 with still sick Sin just made yummy pancake brkfast!” wrote Rachel on Sunday.

In April, the affianced couple opened up to Celebrity Baby Scoop about their hopes and dreams for Sin’s future: “We want the world for Sin. He can be anything he wants to be, the sky’s the limit. As long as he doesn’t hurt himself or others we will be proud of whatever he achieves,” said Rachel. “We plan to teach him to love all walks of life, culture is the best thing to have and to be confident and stand up for what he believes in. Oh, and Destin wants him to be a scientist.”
