Last night my girls went to bed at the same time but that's because we were out and got home after both of their normal bedtimes. Typically though, my youngest goes to bed an hour or so (give or take) earlier than my 2.5 year old. They wake up about the same time in the morning though which is around 8am, so it's not bad.
Do your LOs go to bed at the same time or do they have different bedtimes?
