Molly Sims Covers Fit Pregnancy, Talks "Necessary" C-Section With Son Brooks and Birth Plan for Baby No. 2!

Supermodel also reveals what's easier about expecting her second child as well as what's just as tough!

Molly Sims makes pregnancy look easy and breezy, but don't be deceived!

The expectant model-actress tells Fit Pregnancy's February/March issue she "had a difficult time" carrying her now 2-year-old son, and so far, pregnancy No. 2 hasn't been much easier!

"When I was pregnant with Brooks, I started feeling ill at around 4 p.m. every day during the first trimester. But with this one, I felt hungover from the time I woke up to the time I went to sleep," she tells the mag. "I'm 41, so I had an ultrasound and blood test to make sure everything was OK. We waited until we got the results at 14 weeks to tell anyone, but my in-laws came to visit early on and they said I looked green!"

She did, however, learn "not to freak out over every single symptom," she says, "and now I know exactly how many onesies I need when the baby arrives. I don't have the anxiety of being a first-time mom. Moreover, I know to wear my Spanx tights when I go out, and my T.E.D. compression hose when I fly to prevent blood clots."

Molly also figured out the first time around that sometimes nature dictates what birth plan is needed. "First, I had a velamentous cord insertion [when the umbilical cord inserts into the fetal membranes rather than the middle of the placenta, causing a higher risk of rupture]," she recalls. "The doctor monitored me closely throughout the pregnancy, and I had a scheduled C-section to protect the cord, which was necessary, but disappointing. This time, I don't have the same condition, so I'm not opposed to a VBAC [vaginal birth after Cesarean]."

Of course, what really matters to Molly, hubby Scott Stuber and their son Brooks is that mom baby No. 2 (a little girl!) is healthy and happy when she arrives!
