In the plot where she has a baby, Natalie takes Gabe to her parents' house to tell them she's pregnant.
She arrives unannounced, which may explain her mom and dad's initial harsh judgment. But Natalie is 22 years old, and they treat her like a teenager.
Her mom is very judgemental about the fact that she and Gabe ended up in this situation when they aren't even "a thing." Instead of showing her support, her mom also loudly complains about how this baby is going to ruin her future plans.
Natalie essentially has to beg her parents to let her move home. And all of this is made even more awkward by the fact that Gabe just has to sit and listen to them argue.
