“I’m officially obsessed,” Murgatroyd wrote as the caption for an adorable Instagram photo featuring Shai snuggling with an over-sized, stuffed elephant and holding a sign that reads, “Today I am 12 weeks old.”

It turns out Shai’s milestone wasn’t the only cause for celebration in the Chmerkovskiy/Murgatroyd household. It was also Chmerkovskiy’s father’s birthday! The professional dancer posted a cute snap of the proud grandpa and Shai on Instagram, writing, “Birthday Boys! 57 years young OG and 3 months old YG!”
