On Thursday, Oct. 18, Eva Longoria‘s baby boy Santiago turned four months old and the new mom couldn’t help but gush about her first child on Instagram. Eva, 43, shared a cute photo collage of Santiago smiling at his mom while laying down in his crib. And she noted how much happier she has become since welcoming Santiago into the world.

“I still look at Santi and wonder how my body created and nourished this little bundle of love,” Eva penned the caption. “Truly a miracle! From the moment he was placed in my arms, I knew no love like this before. Happy 4 month Birthday mi Santi precioso!!! 😍.”

Eva is obviously enjoying every moment of motherhood with her cute new baby. She added that Santiago needs to grow at a slower pace so that she can enjoy more precious moments with him. “It’s going by too fast,” she shared.

Once Eva posted the sweet snap of her baby, her celebrity friends took to Instagram to give her son a cute shout-out in the comment section. Fantastic Four actress Jessica Alba wrote, “He’s very sweet,” and Melanie Griffith even said, “OMG! He’s so adorable and so big! So fast!”

In fact, Eva has been enjoying spending time with Santiago so much that she has reportedly been thinking about having another baby. According to OK! magazine, she doesn’t want her son to grow up without a sibling. “She figures why wait? She’s 43 and she’d like to give Santiago a sibling who will be close in age,” the source said. “That’s partly why she’s in no hurry to lose her pregnancy weight.”

If Eva decides to grow her family even more, then her Instagram would be flooded with even more cute baby pics. She has already posted a couple of shots of Santiago visiting her at work, meeting her friends, and showing off his musical talents. Here’s hoping Eva will welcome another child very soon!
