"On my older babies I did and I had tough times doing it, with a newborn it's very tough, they're fragile, they need a mother's touch, that's not a father's time, so I said, '... don't tag me in till me and the baby are on terms of 'Stop!' and he can listen to that; I don't want to deal with that new, new.'"prevnext

"When you step into immediately having a 16-month-old — I feel like I know how to deal with 2-year-olds pretty accurately now, but an infant is a whole different story, because when they cry, you don't fully know why they're crying," Rhett said, The Boot reports.

"The best thing [about being a mom] is just the love you feel for your baby," she told Entertainment Tonight. "The breastfeeding, that bond, and honestly, this was the first morning where she didn't wake up to us, but when she wakes up, and her little eyes open, and they see you, this smile... and babies have innocent smiles, they don't fake anything. They let you know exactly how they're feeling."prevnext
