Kendra Wilkinson has found the secret to making it through the morning sickness: having a great husband by her side!

The mom-to-be, who attended the QVC Red Carpet Style event with Hank Baskett on Friday in Beverly Hills, told PEOPLE the pro football player has been nothing but patient throughout the pregnancy.

“Hank’s been spoiling me so much! He’s pretty much saying, ‘Whatever you need to do this pregnancy, do it,'” Wilkinson, 28, says.

“I’m here [and he’s also] working, but he’s making sure if I need to sleep in [then] he allows me to sleep — and sleeping in meaning noon!”

Other than the occasional craving for caramel apples, the reality star — who’s expecting a girl in mid May — admits pregnancy has completely changed her eating habits — for the better!

“I’m all about oranges. I have to have oranges and mango. So it’s more sweet, more fruity, cold. Salads, a lot of salads,” she says. “I’ve been eating so well. I’m healthier now than I’ve ever been in my life. I’m eating clean, organic and low carb.”

But Baskett isn’t the only one supporting her through the final months. The couple credit their son, Hank IV, with being very involved in the pregnancy process.

“Hank knows more than he should know. I believe that when it’s time to teach them about sex and what happens in life, why not teach them? The earlier the better — we have nothing to hide,” she explains.

“He asks stuff … not just where the baby comes from, but ‘How did the baby get in there?’ That one tricks me sometimes, but we find a way to tell him.”

Wilkinson adds, “He knows what’s going to happen [on my] due date. He asks, ‘When am I going to see my baby sister?’ every single day.”

The 4-year-old even offered his input when the couple were deciding on a name for their daughter.

“We involve him in everything so he likes the names we have picked out so far,” Wilkinson says. “They’re all unisex names, names that could be for boys — that are meant for a boy — but could be for a girl.”

The family is all looking forward to adding a baby girl to the mix, but Baskett has already warned his wife that their daughter will steal his heart from the start.

“I’m going to have my little princess tomboy and she’s going to have me wrapped around her little finger,” he tells PEOPLE. “She’s going to get all of the hugs and love that mama gets. I hope [Kendra’s] ready to share because I know that’s going to be my little girl and I’m excited.”
