another ? for moms of 2 kids in 1 room

do they tend to constantly wake each other up? My 5 mo. old wakes at like 6 and then goes back to sleep for like 2 hours after I nurse her. I am wondering if the 23 mo old will wake up when she hears her at 6, and then not go back to bed. What about when one wakes up crying in the middle of the night, does the other wake up right away too?? thanks!

We had to wait to move our two together for a while because Gianni woke up so much. Now, he still does wake up but she doesn't usually wake up. I think once she did (she's 2) and cried and went back to sleep.

Overall, they seem to just ignore each other somewhat.
