Megan Fox claims her youngest son is a beast

The 28-year-old actress, who also has son Noah, 23-months, with Brian, told UsMagazine.com: "He is nearing six months. We did just take him to the doctor, and he's an enormous child."

She added: "He's in the 95 percentile for height and weight. So I've got a beast on my hands."

The actress is besotted with her sons and enjoys watching them achieve new milestones.

She added: "Bodhi is finally starting to talk a little bit."

Last month, Megan admitted she feels "a lot of guilt" about being a working mother.

She said: "Before you have kids you really do not understand how much work it is and how consuming it is. And then you have one and you're like, 'Oh my God, my baby is my whole world.' Every moment of the day is dedicated to this one baby and then all of a sudden you have two babies! Their needs are so different.

"It's really hard to manage because I also don't let them watch TV. It's not like I'm going to sit Noah in front of the television so I can take care of Bodhi. I have to figure out how to incorporate Noah into the process and have him help me take care of Bodhi and make sure he doesn't get jealous and make sure nobody's neglected and everybody's needs are being met. As a mom it's hard because I don't feel like I'm ever giving either one of them 100 percent of my attention or 100 percent of myself, so I carry a lot of guilt."
