The year 2020 was the one that changed life as we know it -- and for some familiar faces from MTV, that also meant some shifting family dynamics. Translation: brand-new, and very cute, babies.

Whether it was mamas from The Challenge welcoming their first offspring or a teen mom 2 giving birth to her fourth (!) son, we're taking a look back at the infants who made their grand debut and the cast members who made pregnancy announcements this truly unique year.

First, here are the little lads/ladies who were born in 2020:

Kailyn Lowry's son Creed

Melissa Reeves' daughter Vienna

Amanda Garcia's son Avonni

DC Young Fly's daughter Nala

And these mamas will give birth to brand-new additions in 2021:

Chelsea Houska
