awake sooo early!

well my 2.5 year old thought it was ok to get up this morning at about 5:15am. NOT OK! Would have been if he'd gone downstairs into the playroom and played but instead he went to the playroom and yelled for me to come play. UGGG! I was having such a good sleep too! luckily he didn't wake the baby so I got up to put "Elmo in grouchland" on for him and for me to drift off to sleep on the couch. until 7am when the baby woke up. not so bad but I'm sure by 10:30 I'm going to be needing a nap along with my 2 yr old. we've tried a few things but so far nothing is working. I've told him when the sun comes up he can get out of bed (no good, we bought a baby gate to put across his door but when he wakes up opens his door and sees the gate he screams and cries (definitely not good). I've offered to put an alarm clock in his room but then he thinks it's like a time out...I dunno what to do anymore!?! next on the list maybe "spiking" his cup of milk at bedtime! ;-) (as if).
