In the new image, Tatum sits on the kitchen counter, wearing an army green tank top and a matching hat with a smiley face patch that perfectly matches his hazel eyes.

The toddler is holding an apple and behind him is a lush green plant.

Another reality TV star commented on the super cute photo.

Teen Mom’s Kailyn Lowry, 31, wrote, “He’s so cute and I still see so much of Rob,” she wrote, referring to Rob Kardashian, 36.

Khloé replied ‘@kaillowry aww, thank you! He reminds me so much of my dad and my brother, it’s wild,” adding two heart eyes emojis.

Tatum turned one on July 28 and in true Kardashian style, Khloé celebrated her ‘SONshine’ with an epic party.

She shared photos from the party on Instagram and posted a lengthy tribute to her youngest child.

The Keeping Up With the Kardashians alum — who shares her two children with her ex-boyfriend Tristan Thompson, 32 — wrote about how proud she is to be his mom.

‘So proud of the love and laughter we have in our home. So proud of your beautiful, gentle, loving, infectious spirit. You light up every room. There’s no denying that everyone smiles when they look at you! Especially where she is so proud to call you hers,” she wrote.

Khloé went on to write about how Tatum changed her life and how much she needed him in her life before changing the words of the song You Are My Sunshine to You Are My SONShine.

And Tatum’s first birthday isn’t the only big moment in her kids’ lives.

Granted, five had just started kindergarten and the mother of two celebrated with an epic photo shoot with a huge backdrop that looked like a sheet of notebook paper and had “First Day of Kindergarten” written on it.

The background was surrounded by pastel-colored balloons and Tatum posed in front of it in her school uniform, consisting of a white shirt and a blue plaid skirt, looking sassy with one hand on her hip.

‘For anyone wondering: no, I’m not doing well! Next up is prom,” she captioned the post.
