The first photo of Alyssa Milano's new baby girl Elizabella Dylan Bugliari has arrived. And could anything be sweeter?

Milano not only introduced the world to her daughter but also shared the moment when her 3-year-old son Milo met his little sister.

"Milo meets his baby sister for the first time," Milano wrote on Instagram, alongside a picture of her two children.

In the photo, the little boy can be seen holding Elizabella's tiny foot.

The excited mom recently tweeted her feelings of joy towards her new edition and expressed her gratitude for the swell of warm wishes from her fans.

My daughter! My daughter! My daughter! Elizabella has made my heart swell and ache with love. Thank you for your sweet messages❣

And Milano also shared a personal mommy moment on her Twitter page, simply writing "Breastfeeding."

The "Mistresses" actress seems to be enjoying this phase of motherhood as much as her pregnancy. Milano opened up about carrying Elizabella in the August/September issue of Fit Pregnancy magazine.

Regarding being pregnant with the little girl, the star gushed, " I love it. I don't think it's as romantic as we project it to be through the media, but I think what the body goes through is miraculous. It's such a cool thing to experience. I feel blessed that I'm getting another chance to do it, especially at 41."

Milano is very aware, however, that her role as mom is different now that she has two little ones on the brain.

Reflecting on some advice that she once received, Milano told the Fit Pregnancy, "Someone said a wise thing to me when I was pregnant with Milo. 'Savor this pregnancy because it's entirely about this baby, but your second pregnancy will still be about this baby who will already have been born.' That's super true." 

Milano, 41, and her husband David Bugliari,33, welcomed their second child, Elizabella, on Thursday, Sept. 4. The baby girl weighed in at 7 pounds, 7 ounces, and measured 19.5 inches.
