My 2 year old is very loud and hands on when it comes to my youngest, and therefore always waking her up. Coupled with her GI problems, the only way I've been able to ensure she gets a good nap in is to hold her. I know this is creating bad sleep habits, so I was wondering how other moms handled it.

Was your baby able to sleep through all the wake ups eventually? Did you hold the baby or let them cry it out while you tend to the older child(ren)?
