Montessori Sleep Technique
Parents are expected to respect the child’s sleeping patterns. When they are sleepy or tired let them sleep independently. This means that you do not let your child have sleeping associated with something like a pacifier/dummy, blanket, or being rocked or swung. It is best to get your child used to sleeping independently earlier rather than later. One may sit with the child or leave them on their own to fall asleep. Montessori also advises that children need not be wrapped, or be placed in a sleeping blanket as this hinders their movement. A child also need not be in a cot and can be placed on a low bed or mattress on the floor, as mentioned earlier. The child can then choose whether or not they want to sleep or play in their own room.
It helps to think of this as a whole-room playpen with a baby gate at the doorway and to examine every nook and cranny for interest and safety. If the newborn is going to share a room with parents or siblings you can still provide a large, safe, and interesting environment.
Eventually your baby will explore the whole room with a gate at the door and then gradually move out into the baby-proofed and baby-interesting remainder of the house.
Please note that I do not necessarily endorse this method of sleep coaching, this is just meant to be a helpful description of a popular sleep coaching method.
