I see this is an old question. How did you end up solving your problem ?

I agree with mom888. I’d try and stagger them so one of them goes to sleep first and then the second.

maybe it will be no big deal if the 2 y.o misses the sleep during the day. might sleep in a little more but you will be able to deal with getting ready in the mornings.

An hour apart for bedtime is actually not too bad. Considering the 2 yo goes to sleep earlier, can you train the 4 yo to know how t go to bed quietly so not to disturb him . My kids loved their sleep and I was fortunate that both were sound sleepers and were not really distracted unless you make a very loud noise . Unless you have a noisy household , there is no reason why anyone can’t go to be bed quietly without disturbing others .

we have a 3 yo and and a 7yo boy sharing a room we put the yongest to bed at 6.30 to 7 pm and allow the older one to stay up till 7.30ish we have a little light that you can turn on next to the older child. we turn this on and read him abook at 7.30. the younger one is so asleep by that time it doesnt wake him up. If the younger one drops his sleep during the day it should work out putting him to bed first. The older one is old enough to know he should be going to bed after the younger one now so it might stop a few issues. We also have another girl that goes to sleep at the same time as the older one. Dad does one while i do the other.

I am having the same problems with my 3 and 4 year olds but I have just been persistent with them, checking on them, taking distracting items like toys and cupboards out of their room.
