I'm a girl and I cried a lot when I was 12. Nope...it wasn't hormones because I didn't start my period or anything until I was 15. I was a late bloomer. But, everybody made such a big deal about me turning 13....becoming a teenager.
I was like, "Can't I just get through being 12 first? At the stroke of midnight one day I'm a teenager. I'm not a kid anymore? My life is over? It's the childhood apocolypse? What does this mean?"
I'm sure boys must go through the same thing.
They're not a little, little kid but they're a long way from being grown up.
He might just be having a hard time controlling his emotions right now and not even know why.
My son is frigging hilarious. I mean, make you laugh until you pee funny. He went through a phase where he got really upset because he thought we were laughing AT him or making fun of him. He got really sensitive all the sudden. But, he certainly did grow out of it and I'm happy to say that he inherited the funny gene from me. He loves playing practical jokes or pulling somebody's leg and he has it figured out that if you're funny, people are going to laugh. But he did go through a thing where he questioned it. He got self conscious.
If you ask your son why he's crying, he might not even know. Maybe he's tired or getting ready for a growth spurt.
I bet he'll come out on the other side of it okay. Just try to be patient with him. Don't let him use crying as a way to get out of something like chores or taking out the garbage. He can cry and take care of animals at the same time.
Let him know some days you feel like crying too. Get it out and over with and move on to the next thing.
