My grandson is almost 6 months. My wife and I several times had to take him overnight or even sleep in their guest room so they could sleep. How anyone manages without family support, I have no idea.

Take solace, though. Right now she pretty much only needs to communicate that she is hungry, tired, or need to be changed. Before you know it she will have a lot more to say, but the tools she uses (screaming her head off) stay pretty much the same. Sometimes words give you context clues, but I find most of us lack the self-awareness and emotional regulation required for clear verbal communication until sometime in our thirties or forties.
