I have a boy who is living with me in my house, his parents are as well. Whenever the smoke alarm goes off in our house, my daughter will cover her ears and say mommy as loud as she can. I taught her not to be afraid of it but to yell for me when she hears one. However this little boy, will jump and laugh and play like nothing is happening. I am worried that if there was an actual fire or emergency, he will just stand there laughing because of the noise from the alarms. They do not bother him at all. Is this a problem?
