Alyssa Milano debuted the first photo of her newborn baby, Elizabella Dylan Bugliari, on Instagram on Saturday, September 6. Alyssa and her husband, David Bugliari, welcomed their second child together on Thursday.

The host and judge of "Project Runway: All Stars" posted a black-and-white picture of Elizabella's tiny legs being wrapped by big brother Milo. She captioned it with, "Milo meets his baby sister for the first time."

Alyssa opened up about her decision to have children in her 40s in the August/September issue of Fit Pregnancy. "I loved waiting a long time to be a mom," the 41-year-old actress told the magazine, "When Milo finally came, I thought - this is what I've waited for my entire life. I wish I could sleep more, but it's not like I wish there were other things I could be doing socially or for my own benefit. Because I really feel like he's completed me."
