Khloe Kardashian dedicated an Instagram post to ex Tristan Thompson for his birthday, posting a photo of him bonding with their kids. After that was posted, Maralee Nichols shared a photo of her cuddle session with her son, Theo, who she had with Thompson.

In Kardashian’s post, she gushed about how Thomspon was a great father to their children.

“Happy birthday @realtristan13 You are truly the best father, brother & uncle,” she wrote. “Your love, attention, silly dances, hugs, carpool rides, bedtime rituals, the way u show up for them. All of the above means more than you’ll ever know to your family of littles.”

Kardashian continued, “My birthday wish for u is that u continue to crave change, healing, and transformation. Be strong, be kind, be patient, be free. Continue to Make your soul and your mommy proud. Happy birthday baby daddy.”

The reality star included a photo of Thompson with their 4-year-old daughter True and their 7-month-old baby boy, but the name is unknown. Thompson’s 6-year-old son, Prince, who he shares with ex-lover Jordan Craig, was present in the picture.

Nichols followed with a photo of her and baby Theo sleeping on her chest on her Instagram Story. Theo’s head was turned, and Nichols’ eyes were closed in the picture.

Last year, Thompson confirmed he was Theo’s biological father, yet refused to be in the child’s life, having referred to (adorable) baby Theo as a mistake in revealed Snapchat messages and begging her to get rid of the baby.

“I’m engaged but I will be married soon,” he texted. “I told you I won’t and can’t be in the child life at all by no means…Why not wait till [you] find the right person to have a family with. Why would you want a baby with a man that’s engaged. You wanna keep a mistake.”
