First Jill, then Jessa, now Josh - the Duggars are slowly breaking their social media silence and only posting good news.

The "19 Kids and Counting" star and his wife, Anna, both took to Instagram on Tuesday to wish their middle child, Michael, a happy fourth birthday. Josh posted an adorable photo of his son, who is sporting an enormous grin on his face, with a caption reading, " HAPPY 4TH BIRTHDAY MICHAEL JAMES!"

"Happy 4th Birthday Michael James! #Big4 #HappyBirthday #Michael," he captioned the same photo on Twitter.

Anna, who is pregnant with the couple's fourth child, posted a short black-and-white video of her son blowing out his birthday candles, with the caption, "So glad to be in Arkansas celebrating Michael's 4th birthday -- we love you Mikey!"

This is the first time the family has posted since reports surfaced that the 27-year-old reality star Josh molested five underage girls as a teenager. After his past was made public, he released a statement to People apologizing for his actions.

"Twelve years ago, as a young teenager, I acted inexcusably for which I am extremely sorry and deeply regret," he said. "I hurt others, including my family and close friends. I confessed this to my parents who took several steps to help me address the situation. We spoke with the authorities where I confessed my wrongdoing, and my parents arranged for me and those affected by my actions to receive counseling. I understood that if I continued down this wrong road that I would end up ruining my life."
