The difference is, this is 'school.'
Not just extracurricular activities.
Kids, 'know' that 'school' is different.
And yes, kids this age DO get separation-anxiety.
Its normal.
They are still young.
He will adapt.
Let him talk about it. And you listen.
The key thing is to just let him express.... his emotions/anxieties/worries/stresses etc. So that, he 'learns' to express himself, to you, his Parent.... so he knows you are there for him and he is 'validated' and "normal."
Because he is NORMAL.
But kids, when young, do not know how to instantly 'cope' or manage their emotions. Thus you have to help them.
Let him talk about it, with you. But also, him knowing that this is the way it is. In a warm way.
The book "The Kissing Hand" is great. Get it.
Its about going to school... and Mommy.
This is normal.
For extracurricular activities, go according to YOUR child. If he doesn't like 'sports', then that's fine. He does not have to do that, just because he is a 'boy.'
Find what HIS interests are, and his talents and his likes.
A child, needs to be nurtured for who THEY are.
Then that way, they develop a sense of self and self-assurance and become, "Individuals." Not just about being like everyone else, just because. They learn to follow, their own heart and interests.
Some adults, don't even know how to do that.
So teach him that.
It is golden.
That will develop him, well.
Let him do what is his interests.
My son is 4. Almost 5. He likes martial arts. His sister takes it too. I talked to my son about it and taking lessons. He told me "I like it and want to, but I am not ready yet...."
I respect that. He KNOWS himself. Because we nurture him, and his ability to express his emotions.
Teach your son to know himself..... via his emotions and how to say it and know it.
all the best,
Susan
