The former Playboy Playmate and her husband Hank Baskett welcomed their first son, Hank Baskett IV, in 2009.
Now the former Girls Next Door star has opened up about her struggles following his birth as she tried to lose her baby weight and adjust to motherhood.
Wilkinson admits she became moody because the pregnancy wrecked her famously impressive figure and she felt pressurised to return to her former glory.
She tells People.com, “I felt like I had to be a different person. I had to be conservative and wear turtlenecks and be someone that I wasn’t. Now that I have my body back and I feel good again, I have the perfect amount of balance. It’s all about finding the balance.
“It got pretty bad, (but) not to the point where I would harm my family. I was a great mom and did what I needed to, but I was definitely very depressed. (Motherhood is) a big change in life and it happened overnight.
“At the time I was doing whatever I could for the baby, but I lost myself and it was really frustrating. Being in the spotlight is a lot of pressure about losing the weight, (especially) coming from the Playboy world.
“A lot of women suffer from PPD (postpartum depression). It needs to be talked about.”
