Final answer:
Gina's expectation of her one-year-old daughter being fully potty trained is not developmentally appropriate.
Step-by-step explanation:
According to the information provided, Gina gets angry at her one-year-old daughter, Brandi, for wetting the bed, claiming that Brandi has been potty trained since she was less than 9 months old and 'she knows better.' However, it is important to note that children typically achieve full daytime bladder control around the age of 2-4 years old and nighttime bladder control around the age of 4-5 years old. Therefore, it is not developmentally appropriate to expect a one-year-old to be fully potty trained and have control over their bladder.
