Honestly I would go with the flow. Both my boys have settled into their own routines. Jack used to go to bed quite late when he was that age. Now at 2 he goes down at 7pm with no fuss. Ever. I believe they settle into what they need so watch the sleep cues. Tom on the other hand has been going down for the night around 5pm. This is when he is ready to go down and trying to keep him up only causes problems so again, I go with the flow. I am sure he too will adjust over time as he grows up (too quickly LOL!).
