My boys go to bed at 6:30 each night, they get up at 6:30 in the morning with one feeding in between. This seems so early to me for bed but they absolutely will not stay up any later than that. They will literally just pass out if we try. That or have a meltdown.

. Is this too early? Will they stay up a bit lat as they get older? thanks!
Re: Bedtime too early?
Not too early. My boys would love bedtime to be 6:30 every night. Unfortunately we can only do that early on the weekends.
During the week, when we pick them up from DC, we normally don't start the routine until 7 or so, but those days they take a snooze in the car on the way home.
4 Fresh IVF cycles + 1 FET where embies didn't survive the thaw = 2 perfect little men!

I think it's a great time. My older child went to bed at 6:30 every night (she pretty much dictated this. Like you said, if she stayed up later....meltdown). She now goes to bed at 7:00 (only 30 minutes later). I love the early bedtime because it also gives me an evening. DH and I can eat dinner and have time to ourselves.
The twins are in bed by 7:00 at the latest.
that's what ours do. It's early but you do your evening baby free.
our twins sleep from 6:30pm to 7am.
6:30 is a great bedtime, don't change a thing. At that age my girls were going to bed between 6 and 6:30pm. They kept that bedtime until I became a SAHM at 11 months old, then it got pushed to 7pm and they were sleeping until 8:30am, but my girls needed more sleep than the average baby. Starting at 4 months they no longer got up anymore at night. They went to bed between 6 and 6:30pm and slept straight through until 8 am when I had to get them up to go to daycare in the morning.
After 2 rounds of IVF & 2 rounds of FET, we were blessed with identical twin girls!
My twins bedtime has been 7pm for at least the last 3-4 months. They will be 1 year tomorrow and have progressively staying up a little later but no more than about 15 minutes or so. I anticipate this to keep happening and eventually we want to try to move their bedtime to 7:30pm or 8:00pm but for now, 7pm is what works.
I do not think that 6:30pm is too early at all.
