Do you put a cup (straw or sippy) in the crib with LO at night? If so, how old was your LO when you started doing that? We've been having some sleep issues which I'm pretty sure is due to molars coming in but there have been a couple times when I went in to settle her down I brought the straw cup with me and taking a drink seemed to help a little bit. I just wonder if it might help her to have a drink available through the night. Are there any safety issues with this that I'm not thinking of?
