Sleepy
An escalating cry that begins as a mere whine and quickly builds to a nasally full outfit can indicate a nap is on order.
Just like when your baby is hungry, they will show additional signs that they have had enough of the world for now.
Look for yawns, rubbing the eyes, or tugging on the ears is the bedtime alarm. Newborns need around 16 hours of sleep, so you may get well-acquainted with this particular cry.
Occasionally, this can also mean that they are uncomfortable. Check baby’s diaper, make sure they have appropriate clothes on for the weather, and then see if the crying stops.
