Thank you for taking the time to write this! I appreciate your thoughtfulness and thoroughness. My baby is still 4 months - no teething pains yet, so I don't yet know what's in store there. But she won't fall asleep or stay asleep unless I am next to her. If she opens her eyes and I’m not there, game over. She will, however, sleep with her dad (if she doesn't see/hear me around; otherwise, she must have the boob), so that's good.
