My daughter, was not a good waker-upper.
As well as my friends, kids.
Some people just do not wake up well... and they may still be tired. If they did not get a full good sleep.
Now, per my daughter, I LET HER, wake up on her own... and did not interfere. The more you interfere, the worse they wake up.
For some people AND kids... they DO NOT LIKE, to immediately interact when they wake up, NOR like to have anyone in their face when they wake up and do not want to even talk or get all smiley, when they wake up.
My sister was like that too.
NOT all people, are cuddly when they wake up.
Go by your child's cues.
Or he will just get more irritated.
My Mom, was and is, a real cheery waker-upper and a total morning person. She drove me NUTS... as a child. Because she'd expect everyone to wake up like her... all interactive. UGH.
Versus, me and the rest of the family, just wanted silence... when we woke up and to go about it, in OUR own way. Not her way. Everyone is different. It took her decades, to realize that.
Instead of just calling us grumpy children.
She did not know us... and our waking up manner. Our Dad did.
He'd let us be. Then we had NO, problem waking up.
Some people take time to fully... wake. And like to go about it on their own pacing.
Nothing is 'wrong' with that.
Know your child's cues.
My son, will wake up on his own, all pleasant.
My daughter would... IF we let her be. If not, it was just NOT pleasant.
It has nothing to do with being 'naughty' or not. It is just the way people wake up.
Some people just NEED their own space... when they wake up.
Nothing wrong with that.
My daughter has outgrown that now.
She is now 8.
She now wakes up fine.
