(PHOTOS) The "One Tree Hill" alum also shared photos and videos with her baby boy on Instagram Stories. "Meanwhile this perfect creature," she captioned one post. Kramer gave birth to Jace in November. She gave an update to Us Weekly on Tuesday, saying Caussin is less stressed as a parent the second time around. "With Jolie, he was more frantic and didn't know what to do and I think that's with any first parent," the star said. "But at the same time with this one he's just, he's so calm. It's really, really, really nice." "The way that he is with Jace and how he interacts and how he's with me... it's a totally different experience," she added. "And it's really refreshing for both of us."
