A new baby affects a lot more than just the parents in a multi-child home: It also permanently alters the lives of little boys and girls who will become brothers or sisters. Jamie-Lynn Sigler, who announced her second pregnancy early last week, just found the perfect way to include her three-year-old son in the joyous news of her impending baby鈥檚 arrival by enlisting his help with the baby鈥檚 sex reveal.

The Mommy I Didn鈥檛 Do It star had little Beau Kyle do the honors by taking a swing at a ball dad Cutter Dykstra pitched, which contained the sex of her unborn child in the form of a colored powder. She shared the event with her followers on Instagram, making us all privy to their special moment. 鈥淲e are excited to announce, it鈥檚 a鈥.鈥 she captioned the super sweet vid.

As we watch, we see Beau making contact with the ball (yay!) before blue powder explodes into the air, as set to the tune of 65鈥檚 鈥淏lue (Da Ba Dee).鈥 As the growing family makes the realization that it鈥檚 another little boy that will soon be joining their ranks, Cutter is seen raising both fists in the air and Beau looks on in amazement.

Much like celebrity mommy Pink, who threw her daughter Willow a 鈥渂ig sister party,鈥 it鈥檚 a thoughtful, family-oriented way for the couple to share in the experience with their little one, who will undoubtedly be anxious to meet his new baby bro.

Congratulations to the family, little Beau included!
