Dr. Jennifer Arnold took to Twitter to share a sweet photo of her 3-year-old son William Rijin, on Saturday (Nov. 9).
“Can’t believe how fast my Will is growing up!!!” The Little Couple star captioned the image of her son pointing to a pink fish on the floor.
Arnold and husband Bill Klein adopted Will from China this spring. Like his parents, he has a form of dwarfism.
“I walk into a room and see him and I still can’t believe he’s ours,” Klein told shortly after he joined their family.
Last month, the couple revealed that they expanded their family again. They adopted 2-year-old daughter Zoey in India, who also has a form of dwarfism.
