So close to going off on my boss

So I work in the toddler room (ages 2 and a half to 3) at a daycare and my bosses daughter is in my class. My boss likes to come in here 10 times a day to see her kid then she will go back to her office and her daughter will cry and scream for 20 minutes straight. She knows her daughter will get upset and I have asked her not to come in so much so this doesn't happen. Now what my boss does is act like she has to ask me a question then her daughter will see her so she will be all "darn she saw me so I better come in" šŸ˜. She did this today during nap time and her child woke everyone up. How do I deal with this? I'm getting so close to yelling at my own boss its not even funny lol.
