Another hot tip to address babies who flip their schedules, mixing up night and day-- turn down (around 9PM), and then OFF (at 10), all the lights in the house. Keep any night-time babytending very, very dim, quiet, lowkey. Give attention, but not playtime. Their brains figger it out from there if we do not over-stimulate them with light, noise, and facial responsiveness. You act sleepy, they get the idea before too long.
