There's an enormous amount of pressure piled on women to have children in their 20s, but for many of them, that's just far too early in life to have really decided on their plans for a family.
And while many women now wait until later in life before they settle down and start a family, there's still a huge stigma around being an older mum - and vicious trolls online have plenty to say to those who have kids in their 30s and 40s.
One mum on TikTok knows about that negativity all too well, as she's currently expecting a baby at the age of 40 and has been told she must be going through a "midlife crisis" to be bringing a child into the world at her age.
