Hilaria Baldwin can't wait to meet her unborn son

She wrote: "Little #BaldwinBabyBump3 update: all is wonderful! I'm getting REALLY excited to meet him! #366daysoflivingclearly #HilariaLCM"

The brunette yoga instructor already has three-year-old daughter Carmen and 12-month-old son Rafael with her 58-year-old spouse and she recently revealed how she was initially worried about having another baby.

Writing on Instagram about the bond between her two children, alongside a picture of them she said: "Siblings I have to say I was nervous to become a mom. When I was pregnant with Carmen, I was scared that I would not be enough for her. That all disappeared the moment she was born because the love and devotion that immediately appears, is so overwhelming and all consuming. Then I got pregnant with Rafael...I was scared to rock Carmen's world and change her dynamic of being the center of attention--I was afraid I would not be enough for two. Again, as soon as he was born, all of that vanished as my heart only grew and my devotion doubled. Now, I see these two...and I marvel at how deep their bond is. I'm, for the first time, not scared of the arrival baby number 3....because I know that it only gets better and better. SOUND UP FOR THE SOUNDS OF HAPPINESS"
