Children’s sleep issues are among the more challenging developmental stages for parents to master. But biology is on the parents’ side in this one, because sleep patterns mature over time just like other developmental skills.
* Polls tell us that one-third of American children and their parents sleep together some or most of the time before children start school. Co-sleeping varies hugely by culture and ethnicity. So think about what you want to do, and discuss the pros and cons with your pediatrician.
* Make sure your crib is safe (locking rails), that your older child’s ‘big bed’ has side rails, and if you are co-sleeping, that there is plenty of room.
* The human brain is active during sleep, but the deepest sleep is typically at the beginning of the night. Babies spend more time than older children in stimulating REM sleep, with eye movements and irregular breathing. Don’t worry about all that action in your child’s body – it too is growth.
* Start them young – do not ignore the importance of naps, watch for the yawn, and start bedtime early in the evening.
