How do I get my 4 month old to bed at 7pm?

My son is almost 4 months old and he is going to sleep around 9:30-10ish. Tonight I tried doing bath, bottle and bedtime earlier. He woke up from last nap at 4:30 and did bedtime around 6:30 and it was a complete fail. He slept 30 minutes and woke up screaming. Took 45 minutes to get him back to sleep and again, he woke up 30 minutes later screaming. We brought him downstairs and he was so irritable I knew he was tired but he's fighting it. How in the world do we transition him to bed sooner?
