Heather Rae El Moussa Says Breastfeeding Is Hard 'But Very Gratifying, I Love It' Discussing how Tristan made his entrance into the world, Heather revealed she had a difficult experience giving birth. "I had scar tissue built up from a biopsy I had years ago, which affected my cervix softening & water breaking. Once at the hospital I was given 1/2 a pill of Cytotec to soften cervix, balloon went in. 2 hours later I was dilated to a 4. Balloon fell out, then 3 hours later dialated to a 6, then a few minutes an 8 then 15 minutes later my water broke," the new mom shared. "It was time to push!! it all happened really fast. Tristan's heart rate was dropping very low every time I'd push & was staying low. Which was terrifying," she continued. "My doctor told me that we had to get him out right away. I had 4 more pushes and to give it my all & she was going to use a vacuum to help get him out fast or otherwise we would have to do an emergency C-section." Heather Rae El Moussa/instagram, Tarek El Moussa/instagram Heather noted Tarek was "on my right holding my hand, talking me through everything" in the difficult moment. "I pushed so hard all the blood vessels broke in my face and chest. Tarek yelled I see his head, push push push. Our baby boy came out healthy and beautiful, I was in a state of shock it was a surreal experience. I was emotional and drained & so in love already," she shared. "It was scary, but beautiful & I had the best support from Tarek, my incredible @drlisakaramardian and all the nurses at Hoag." The new mom concluded, "We have been in our own private bubble but today we are so happy to share Tristan and some of our our birth story with the world 🤍🤍." "Our baby boy is here 1.31.23," they wrote in a joint statement. "Mama & baby are happy, healthy, tired but doing well. Our hearts are so happy."
