There was an outpouring of love from Derick Dillard and the whole Duggar family for 19 Kids and Counting's Jill Duggar as she celebrated her 24th birthday on May 17.

On his Instagram account, Derick wrote: "Happy 24th birthday @jillmdillard. You're the best wife and now mother to our little son! I love you baby!"

Meanwhile, the Duggar family posted a photo of Jill and her new family on their Facebook page as they wished "this sweet girl" the happiest of birthdays.

"How much we love her," the family gushed. "We have always loved her sweet spirit. It has been such a joy to watch her become a loving wife and a devoted mom. More than all we rejoice for her love for Christ and her devotion to following Him. Happy birthday to our Jill today!"

On the Duggar Family Blog, on the other hand, they posted a collage of photos of Jill during her younger years and wedding day, and some of the other photos showed her spending time with her siblings, her father Jim Bob, and her husband Derick.

They entitled it "Duggar #4 Turns 24" and simply wrote, "Wishing Jill Dillard a happy 24th birthday!"

Jill was born 16 months after Jim Bob and Michelle had their first set of twins, Jana and John, and she revealed that there was always something to do or someone to play with in the Duggar household, so things were never dull growing up.

"Growing up, people would sometimes guess that Jana, John and I were triplets because we were so close in age, or that Jana and I were twins, since we looked so much alike," shared Jill.
