When her older twin daughters return from a weekend at their dad's (Corey Simms) house, tensions – and tantrums – run high.
"I just feel stressed out now," Leah tells her friend. "I forgot today's the first day they've been back. Maybe it's the transition from his house to my house. Ali does good, it's more Gracie."
Soon after, Aleeah Grace sets off in a screaming fit.
"Gracie! Get that right now," Leah shouts. "I'm not playing. You're going to pick that up! You're not going to act like this in front of people."
As she leads her daughter to another room, Leah continues: "Do you understand? I've had enough. I don't know why you're acting like this."
When Aleeah Grace can't seem to calm down and behave, Leah takes her for a spanking.
Do you think she did the right thing? Let us know what you think in the comments below!
