I have a 3yo and a 5.5 month old. My youngest has been co-sleeping in our room. Soon it will be time to get her into her crib in her own room. The problem is, the baby room is right next door, not across, next door with shared wall with my toddlers. My infant is EBF and only falls asleep on my breast. My husband then transfers her out of my arms to her co-sleeper right next to my side of the bed at night. That won't be happening anymore once the baby moves to her crib. I know we are probably going to have to do some CIO. The issue is, this will definitely wake up my toddler. So how do you all do it? Is it anytime the baby cries this will keep the other one up, and vice versa? We had a few miserable nights last week where my toddler was up having bad dreams and as soon as she was asleep the baby was up. Seems like they took turns all night long and this happened three nights in a row. So is this what we should expect from here on out when one is up crying? Any advice? Also, we have sound machine, black out curtains, etc etc and seems both my girls are light sleepers. Is this just the way it goes?
