If you’ve watched Keeping Up With the Kardashians and any one of its several spinoffs, then you’re fully aware of the long relationship journey Kourtney Kardashian and Scott Disick traveled to arrive at the point in which they had their second child, Penelope Scotland Disick, on Sunday.

And we fully expect to get to know her just as we have their first child, son Mason? It’s hard not to feel like we’re somehow part of a baby’s life when we’ve watched them go from bump to delivery and then through their first words and beyond.

Mason and Penelope aren’t alone. Who else have we known from the belly?

Reality TV has given us a glimpse into the private lives of several celebrities and by extension, their adorable children’s lives, as well.

From Tori Spelling to Rachel Zoe, take a look at the babies we’ve known from the belly photo gallery above.
