Yes. Check out the June issue of Glamour magazine-she's on the cover. If you look at the article they don't mention the nursing at all, but they did talk a bit about how busy she is with work and baby and everything. So they had her write down a rough schedule of an average day. It's shown in the mag still in her handwriting and all, and she mentions breastfeeding.
Here, I found it. It goes like this.
5:20 Roman cries(needs a hug)
6:35 Roman wakes
6:35-7:15 change Roman, breasfeed, and play in bed
8: Romans breakfast
8:30 get Roman dressed
9 Debras 15 minutes to shower/dress/pack for day
and on like that-go to studio, Roman falls asleep in car and finishes his nap in a crib at the studio, they nurse again around 11, etc..
I thought it was cool. It wasn't really part of the interview but I just love this woman because dammit even if htey won't ask about it she's still making sure people know she's breastfeeding.
