Blac Chyna has learned some "cool" stuff about motherhood and now feels "obligated" to breastfeed.

The 28-year-old reality TV star - real name Angela Renee White - is expecting a baby with partner Rob Kardashian in November (16). She already has son King, three, with former fiance Tyga, the rapper who is currently dating Rob's sister Kylie Jenner.

Chyna was speaking to pal Amber Rose on her Loveline With Amber Rose podcast on Play.It this week about her pregnancy and she explained that she feels "more educated" on motherhood the second time around.

The pair discussed breastfeeding, and controversial comments made by rocker Travis Barker's ex-wife Shanna Moakler in a 2013 interview, in which the former model slammed the practice as "incestual" and "gross".

But Chyna reveals she is open to breastfeeding with her new baby, and now feels "obligated, in a sense".

"Maybe (it's) my motherly instinct," she pondered. "Just reading and knowing the pros of breastfeeding for your baby, and just recently I found out some new, cool stuff about not cutting the cord and sending your placenta, you can get these pills to take them after to make you and the baby healthy. If you notice dogs and cats, when they have their babies, they eat the placenta. You're like, 'No, don't do that!' But they do, it's a healthy thing. ... I feel like with my second baby, I'm more educated than the first one."

Chyna revealed she is having a baby girl on the first episode of reality show Rob & Chyna on Sunday night (11Sep16).
