Kourtney Kardashian has slammed the unrealistic "pressure" for women to regain their pre-pregnancy figures.

The 44-year-old reality star — who has Mason, 14, Penelope, 11, and Reign, nine, with ex-boyfriend Scott Disick, and five-month-old Rocky with husband Travis Barker — urged fellow new mothers to "be kind" to their changing bodies and accept that their figures will "find a new normal" over time.
