James explained that he and his wife found a doctor in Texas that diagnosed the last two pregnancy losses as "having been caused by an: 'incompetent cervix.' " "A simple surgical cerclage was done, removed at full-term, @vanderkimberly gave birth naturally on the ranch… and here we are," the actor shared. "The medical books say to only look at a cerclage as an option after three late-term losses. Our doctor recommends considering it after one. Spread the word." "Each child brings their own energy, their own manifestation of consciousness, their own lessons. The ones we lost each gifted us with different pieces of the puzzle… leaving us that much more grateful for the ongoing master class we get to enjoy with this sweet, wise little one," James added, going on to thank "everyone in our community" for their support and honoring of their privacy. Kimberly Van Der Beek Instagram "Life is beautiful," James concluded the post. "Life is so full I don't have the words. Jeremiah Van Der Beek, thank you for being here 😍," Kimberly added in a post on her Instagram page.
