Such bliss! Jill Duggar and Derick Dillard shared an adorable set of photographs of baby Israel's first days via their website, which show the little tot (and mom and dad!) looking blissfully happy.

The couple, who welcomed baby Israel David on Monday, April 6, celebrated the first week of his life by sharing an array of super-cute snaps of their firstborn on Monday, April 13.

The snaps show the little boy in various situations since his birth. In the first photo he is pictured while still in hospital, proud mom Jill beaming at him as they cuddle up in her hospital bed.

Next there's a photo of the couple leaving the hospital, Jill seated in a wheelchair being pushed by a nurse, while baby Israel (carried by dad Dillard) is safely strapped into his car seat for his journey home.

Once home the little tot is pictured yawning, and then (even more adorably) while posing in a huge pair of adult sunglasses!

There's also a few pictures of baby Israel's first visitors — including one of aunt Joy Anna Duggar babysitting the swaddled, snoozing baby while she writes a greeting card.

On Saturday, April 11, the happy parents took to Instagram to thank well-wishers for their messages as they adapt to life as a new family of three.

"As Jill and I are settling in back at home after the birth of our firstborn, we wanted to thank everyone for the amazing support we've received from so many during this time," Derick captioned a selfie of him and his wife relaxing in bed. "Your thoughts and prayers mean so much to us. We love you all! #Blessed #Grateful."
