Advice for 2 Year Old and 9 Month Old Sharing a Room....

My 3 year old shared a room with his baby brother from the time he was 6 months and moved out of his cradle in our room. He's always gone to bed first, and we purposely put him down early so he would be in deep sleep when his big brother came to bed. We also use a loud fan next to the crib to drown out any noise. But the baby can scream for 15 minutes at night, never waking up his brother. And the 3 year old goes to bed, whispers his prayers, and snuggles with my hubby or I for about 10 minutes, and rarely wakes up the baby. He loves it when we sleep with him a little bit, so we tell him if he's to loud and wakes up the baby, we have to leave to rock the baby back to bed, and then he gets scared to be by himself. So he's very motivated to be extra quiet, and like I said, most nights they're fine. Good luck!

I had all three of my little ones on a room at one time.
I put the youngest down together at about 7pm. They were three and under 1. My 6 year old went in about 7:45-8:00 but she was always quiet.
They had baths together and then teeth and story then lights out and I always put on a lullabye CD.

Try singing softly to your toddler the whole time you are putting him to bed. Hopefully he'll keep quiet so he can hear you singing. Then continue singing outside of his room for 5 to 10 minutes so he'll stay quiet! I use singing as part of our bedtime routine and it works great. I rely on a few lullaby CD's to build up my repertoire so I don't bore myself silly. Good luck!

It seems like you've got a good system... of course as your baby grows older, the system will change... and the two of them will start going to bed together... but since the current system works well, why change it?

Holy cow! We just went throught the exact same thing a month ago. We finally figured out that it was not doing our daughter any good to learn to sleep in our room at night but naptime was in her crib. We started teaching our two year old 'shhhh aubrey is sleeping. we have to whisper' he caught on pretty quick. She is still a light sleeper (last night he woke her up when I put him down) but it's getting better. We put him down an hour after I notice that she actually fell asleep rather than an hour after bedtime. Some nights she plays for quite a while. It seems to be good timing for now, but we have only mastered it for a few weeks so we're still rookies! You never know when they'll throw a wrench in the plan!Good luck! I truely reached my breking point with the bedtime issues. It's a huge relief to have had the help on here that I did. Hope it works out soon!

We have our 10-month-old baby down at 7.
Then, we do the night time routine with our son ( 32 months). We do the same as before the baby, but in the leaving room instead of the bedroom (pyjamas, remembering the day, "planning" the next day, reading books). Then, we go to the bedroom. Before entering, I always remind him to be very quiet not to wake up his sister. (He knows that if she wakes up, I will go take care of her instead of him, even if we don't say it often).
I sing to him in a very soft voice, kiss him goodnight and leave until the next morning.
It has worked so far.
He woke her up during the night a couple of times because he had nightmares.
When she cries (teething), he doesn't wake up.
