Welcoming daughter Maxwell Drew Johnson on May 1, Jessica Simpson has kept relatively quiet when it comes to gushing about her newborn baby girl.

And if you ask maternity concierge and star of Bravo's Pregnant in Heels Rosie Pope, that's just the way the 31-year-old star should keep it...for now.

"Jessica's been under so much scrutiny for so long, that I really think she needs to keep her baby private and her mothering private for a little bit," Pope, who welcomed her third baby on Mother's Day, tells Us Weekly. "That's the respite she needs to really get her feet under her. Otherwise she's going to be out driving with the baby on her lap feeding it gumdrops or something," Pope jokes.

When it comes to shedding unwanted pregnancy pounds, Pope, 32, also suggests giving Simpson time to get acclimated to motherhood before hopping back on the treadmill. "It is better to lose it hard and fast, though," Pope says of Simpson, who is in talks to shed extra pounds with Weight Watchers. "It's difficult to get it off if you wait too long."
