As Josh Duggar seeks treatment for his infidelity and porn scandal, his son is spending time with the disgraced reality star’s family.

Sister Jessa (Duggar) Seewald posted a photo Wednesday of Josh’s son Michael, 4, holding Jill (Duggar) Dillard‘s baby boy Israel, 6 months.

“When the baby you’re trying to hold is about as big as you are!” the proud aunt, who is expecting her first child, captioned the Facebook post.

Josh, 27, checked into a faith-based rehab center in Illinois in August after confessing to cheating on his wife Anna using the website Ashley Madison.

Josh and Anna have three more kids together: Marcus, 2,MacKynzie, 6, and Meredith, 3 months.

Anna, 27, has been finding comfort in her husband’s relatives, including his cousin Amy (Duggar) King, whose wedding she attended – without Josh – in September.

“I gave her the biggest hug ever when I first saw her,” King told PEOPLE. “That’s when I got the most emotional. I can’t imagine what she’s been through. I would be a disaster.”

Although TLC canceled 19 Kids and Counting last spring after Josh admitted to molesting five underage girls as a teen, his sisters will be the focus of a new series of specials, the network announced last month. PEOPLE first reported news of a potential spinoff in May.
