Everything had been majorly taken for granted before Riley was born. Spending time alone with each other and hanging out with friends had been normal for Cory and Topanga, and sleeping all night had been easy. They were a young, free college couple, living in independence for the first time in their lives.
After becoming parents, their independence died. Dependence was born in the form of a screaming newborn who wasn't able to do anything by herself, depending on her parents to feed her, ease her back to sleep when she woke up, and worst of all, change her diapers.
Parenthood didn't include freedom, nor did it provide alone time, social interaction, or sleep. It didn't provide sanity, either.
