"Israel seems to be adjusting to the new climate, culture, food (via mom's milk), and language faster than Jill and I are," he wrote. "Everywhere we go, people here about and want to see and hold the, 'big blue-eyed, white baby' LOL. Israel is definitely growing and developing fast."
Derick included a couple of pics of all the attention Israel has been receiving from the locals -- and it looks like he's loving it!
While 19 Kids and Counting was cancelled in the wake of Josh Duggar's molestation scandal, TLC announced that it plans to raise awareness about child sexual abuse through a one-hour, commercial-free documentary that is set to air in late August. The Duggars are reportedly going to be a part of this project.
