Could my son get kicked out of preschool for crying too much?

My son will be 4 next month, and he starts preschool in 2 weeks.

It’s half a day, 5 days a week. I’m really worried.

My son is extremely whiny, and cries a lot more than other kids his age.

I worry his teacher will lose their patience with him and ultimately tell me he will be no longer welcome. I really wouldn’t blame her if she can’t deal with him, most people can’t. My husband loses his patience, and my parents and in laws have a difficult time with him too.

I really don’t know why he cries so much, we used to do a lot of fun things, but he would also end up crying at the park, amusement park, library, anywhere. Now I don’t really bring him out anywhere because it’s embarrassing, and he will just be miserable. Sometimes I think he just cries bc he enjoys crying.

If he’s not crying, he’s whining. He literally just lays on the floor whining all day.

I wouldn’t blame his teacher if she doesn’t want him in her class. He is a really difficult child. But has anyone heard of this happening?
