Jill (Duggar) Dillard and Derick Dillard‘s son Israel is reaching new milestones every day.

Jill, 24, took to the Dillard family website Monday to share an update on how the family is doing on their longterm mission trip to Central America.

The TLC star says their 7-month-old son is growing up and learning new things daily.

“Israel has been busy this week showing us new tricks!” Jill wrote. “Every day for the last three days he has learned something new! First it was clapping, then crawling, pulling up into a standing position and waving! He is about to cut his first two teeth, so recently he has been a little fussier than normal. He is usually happy though and loves exploring new areas in the house now that he can move!”

Jill gushed about what a “joy” it is to be working with and visiting families in their area and learning to speak Spanish.

The family is also acclimating to life in a new place and dealing with everyday challenges: Jill said her husband Derick, 26, was “able to find a dentist who could fix an orthodontic piece that broke off.”

Jill and Derick set off on their mission trip to Central America with Israel in July.

In the months since, the three returned to the United States for the wedding of a family friend in August, and to attend their cousin Amy (Duggar) King’s September wedding.

In October, the Dillards flew back to Central America to continue their mission trip, announcing on their website that they won’t be able to make a short visit back to the U.S. again until summer 2016.

Though they aren’t stateside, Jill and Derick stay in touch with the rest of the Duggar family. Earlier this month, Israel met his cousin Spurgeon Elliot Seewald, Jessa (Duggar) Seewald and husband Ben‘s son, via video chat.

Jill, Derick and their son will also star in the upcoming TLC special, Jill & Jessa: Counting On, which premieres in December.

The special will focus on Jessa and Ben getting ready for the birth of their firstborn, as well as Jill and Derick’s preparation to return to Central America.

Jill & Jessa: Counting On premieres Dec. 13 at 8 p.m. ET on TLC.
