Son waking up in full blown temper tantrums

[KingstonMom]

Do you always wake him up or does he wake on his own? I find that my son used to be like this whenever I woke him, now I just let him come out of his room on his own. If I need him up, I'll turn his light on and open his door and he usually wake on his own. This cut down his tantrums quite a bit.
The odd day he still walks out of his room in a whining fit about his friends being here or them playing with his things, but I tell him to gho back to bed until he is ready to come out in a happy mood. It sometimes works. My son is 3.5.
