Alternately you could see if 4 year old could go somewhere else in the house to play as soon as he wakes up. My oldest would've woken up if we tried that, but maybe it'll work for you?
Ideally I want DS2 to sleep later; he is waking up much earlier than needed. I would like for him to learn to stay quiet in his bed until he sees the "green light". Leaving the room would wake up DS1 for sure.
