It was worth a try...

but after two weeks, we have determined that E and R are not capable of sharing a room. They both had been asking for so long, so when we unexpectedly had to get rid of R's paci (apparantly they are not made for 3 year olds who are the size of 6 year olds) and sleep became so difficult for him, we decided to let them try. R forgot his beloved paci when he got to have "nuna" in his room. Unfortunately E doesn't need anywhere near the amount of sleep that R does and she was keeping him up (ie. he became a whiny little mess). So... as of today we are back to each of them having their own room. Thankfully everyone went to sleep quickly and peacefully.
