For years, Kristin Cavallari was the one screaming at clubs or in Cabo on The Hills and Laguna Beach, but now it’s her son Jaxon, 5 months, who has the pipes.

The shoe designer, 27, recently spoke with the Daily Mail about her youngest child, admitting, “They always say the second one is harder and that's very true. Jax is a little bit more difficult. But he is still the sweetest and the best. So it’s fine.”

What makes Camden’s little brother tough to handle? He suffers from colic — a condition in which children cry for more than three hours at a time. Ouch. 

“I was very colicy as a baby, so I guess Jax is a lot like me,” Cavallari said of her son. 

And while dealing with a baby with colic is not a fun task, the former reality star and her Chicago Bears quarterback hubby Jay Cutler are enjoying watching their boys grow. 

Last week the former Dancing With the Stars contestant posted a black and white picture of her little guys drinking milk and holding hands. 

“I can’t handle it,” she captioned the cute snap.
