The mom of one dishes on the hardest - and funniest - parts of parenting her 3-year-old son Sebastian, with ex Wiz Khalifa

Amber Rose knows that with parenting comes 24/7 uncontrollable worry.

“As a mom, you have a million different fears,” the mom to 3-year-old Sebastian Taylor tells PEOPLE in an exclusive interview. “You don’t sleep at night. You think about all the worst things that could possibly happen to your baby, and it really sucks.”

But the constant concern is totally worth it for the trade-off of Sebastian’s unconditional affection.

“I literally almost shed a tear every single time when he hugs me really tight and he says, ‘Oh, Mommy, I love you so much,’ ” the actress and former model, 32, admits of her sweet son, whom she shares with ex-husband Wiz Khalifa. “I want him to do any and every thing that makes him smile and be happy forever.”

Of Sebastian, whom the television host is raising to be a feminist, she says she’s proud of how quickly he’s picking up on bigger words — even though sometimes the way he uses said words is pretty hilarious.

“I gave him a piece of strawberry gum, and he was so dramatic when I gave it to him because he said, ‘Oooh, Mommy, this gum feels so therapeutic,’ ” the protective mom of one says. “And I just laughed on the floor until I cried.”

On a related note, she adds that if she could give moms a piece of advice, she’d tell them to read to their kids every night to help expand their vocabulary early.

“I read to Sebastian every single day when he was in my arms, and now he can articulate a sentence like no other, and he’s 3 years old,” Rose says proudly. “He knows every big word. And every time your baby says something like, ‘Oh, this is relaxing,’ you be like a thesaurus and you give [them] a different way to say it every single time so they learn.”

While Rose doesn’t have any moments in her three-year history of being a parent that she would do over, she is candid about the fact that she truly had no idea what to expect at the beginning, even though she tried her best to prepare.

“I read every single book, when I was pregnant, about being a mom and being pregnant and doing the right thing, and then I had my baby and I was just like, ‘What the hell do I do now?’ ” she admits.

Luckily, the style-adventurous mama figured it out pretty quickly.

“Your maternal instinct comes in, and you figure it out along the way. And that’s the fun part about it,” she says.
