*Angela Simmons was preparing for an October arrival of her son with fiancé Sutton Tennyson – but the baby had other plans.

The “Growing Up Hip Hop” star and daughter of Run D.M.C.’s Rev. Run actually gave birth to little Sutton Joseph on Sept. 22 – at just 36 weeks and 4 days.

“We thought we had another month to get the nursery ready,” Simmons, 29, says in the current issue of PEOPLE.

The nursery was eventually completed, and the couple showed off first pics of the room exclusively to People.

“Angela and Sutton were such a pleasure to work with,” says nursery designer Vanessa Antonelli. “It’s so refreshing when both parents show tremendous interest in the design process. They knew they wanted the Nurseryworks Vetro crib for the little one, and I created a room around it using custom art like the tape art focal wall by Eric Klein and the DJ’ing Cookie Monster by Art of Perego.”

Though the nursery is complete, Simmons admits her little boy isn’t sleeping much in the crib.

“He is a hungry boy,” she says. “He’s up every few hours wanting to eat. It doesn’t leave a lot of time to close my eyes. But it’s all worth it.”

Simmons also says she’s relying heavily on the support of her family — particularly her fiancé.

“He’s been so helpful, doing middle-of-the-night diaper changes and everything,” she says.

Those diaper changes have proven surprisingly difficult for Simmons given her son’s preference to be constantly dry and clean, but disdain for the process of being changed.

“He hates being dirty but never wants to be naked,” says Simmons. “We try and get the new diaper on him as quickly as possible to calm him down.”

Simmons is still working on planning her wedding, but at least for now little Sutton is taking priority.

“I’ve always wanted to be a mom,” she says. “So I’m loving every minute of it.”
