Proud mum Katherine Heigl shares sweet new pics of her baby son

She gave birth to son Joshua Bishop Kelley Jr. last December. 

And on Thursday, Katherine Heigl, 38, shared an adorable photo of her little one on Instagram, the Daily Mail reports. 

In the cute snap, the infant appeared over the moon and in midst of a laugh. 

"Thanks Aunt Christy Kelley for this gorgeous handmade quilt for little man!," began the star. 

"You've totally inspired me to try my hand at quilting!! This one's going down in the Family Heirloom Book for sure! #thoseheavenlydays #madewithlove."

In the photo, the three-month-old was snuggled up in a knit sweater, matching baby booties and a pair of trousers.

Following the arrival of Joshua Jr., the 27 Dresses star confessed to People that her weight gain during pregnancy was one of her the "rough" parts of a rather "easy" pregnancy. 

"What was rough with the pregnancy was just the terror of the weight gain," she began. 

"You're going to gain weight; that's just part of the whole thing. Stepping on that scale every month in the doctor's office was heartbreaking for me because I'm used to watching that so closely, and the moment I start putting on weight being like, 'Oh no, I have to rein it back in.''

"I tried to be as healthy as I could about it and not go crazy and go over the top with weight gain, but I still gained a lot for me."

Having gone up an estimated 40 lbs (18kg), she quickly dropped weight after the first few days. 

"Within a week and a half after he was born, I dropped so much weight, and I was like, 'Oh my God, my body really does know what it’s doing, I’m just going to back off and not stress about this.'"

As of January, she still wants to lose another 20lbs (9kg), but won't pressure herself because won't be "going on back on camera" for a bit, so she will take it slow.  

The actress will next appear in the drama, Unforgettable, out April 21. Filming for the movie took place in 2015.
