Do you have close in age Siblings in sharing a room?

At what ages did you put them in the same room? Were you still doing night feedings? Any bedtime recommendations- who goes to sleep first or same time? Tips for them waking each other up?

We have 2 boys (19m and 1m) and a small place so they will need to share a room sooner rather than later. Right now big brother has been in his nursery since he was about 10w old. Baby brother is still in bassinet in our room but is quickly outgrowing it.

Our toddler is an early riser already and our 1m old wakes for a feeding between 4-6am. We’d like to have them in the same room soon but I’m worried the baby will wake the toddler up super early and the toddler won’t go back to bed.
