HilariaandAlec Baldwin’s sonRafael Thomasis on the mend after breaking his arm “really badly” while playing at the park.

The soon-to-be mom of seven shared onInstagramThursday that she and Alec were at the hospital “until pretty late” last night while in the emergency room with their 6-year-old son, who now requires an arm cast for “quite a while.”

“This is a part of being a parent that is so heartbreaking,” Hilaria wrote alongside photos of Rafael at the hospital. “We were with the babies when it happened and to get that call makes your heart sink. His little voice on the phone “I want my mommy”…knowing even the 20 min to get to him is 20 min too long. To not be able to immediately take away their pain and fear…oooof nothing prepares us for this, right?”

“We were at the hospital until pretty late and then we made a bed on our floor (wild sleeper, was afraid he might fall off our bed). How many times he called out for me last night, I do not know,” she continued. “At one point I heard him whispering to himself, recounting what happened, saying over and over: ‘I broke my arm.’ We are relieved that, while it will be a long recovery road, he is certainly on it 💕”
