The Counting On stars are already parents to two-year-old son Israel, aka Izzy, and even though he might be too young to really know what the duties of becoming a big brother entails, his grandparents and his parents are sure that he’ll fit into the role just fine.

“Israel didn’t really understand what was happening but he’s just excited because other people are excited, so he’s just excited about his new little baby brother,” Derick said in a TLC video announcing the couples’ pregnancy back in January, and Jill added, “I know that Israel and this little one will be best friends.”
