The show follows their life with their four biological children Lily, Merritt, Priscilla, and River, and their newly-adopted baby boy, Gus.
It seems as though Gus is growing up right before our eyes!
On Easter Sunday, he started crawling for the first time and we thought that was a big deal!
On Monday (Aprill 11), Jessica shared a cute photo of Gus laying on the grass in a bathing suit, revealing he took his first swim!
And now, she revealed on Instagram that he hit yet another milestone – he said his first word!
“These two Robertson boys say hello!” she captioned the sweet photo. “And yes, Gus’s first word was ‘dada’!!!!“
Before we know it, Gus is going to be running around the Robertson house and going on his first duck hunt!
