Newborns are very sleepy but hard to sleep may be due to physiological reasons, such as hunger, urination or high temperature, etc., or may be due to pathological reasons, such as respiratory tract infections. 1. Physiological reasons: may be the newborn appeared to be hungry, or urinate and poop, or indoor temperature is too high, cover too thick, etc., so that the newborn is uncomfortable, even if sleepy, but also difficult to fall asleep. Parents should feed the baby in time, change the diaper in time, and improve the sleeping environment. 2. Pathological causes: such as nasal congestion, respiratory tract infections and other obstruction of the respiratory tract, resulting in poor breathing. It may also be due to gastrointestinal dysfunction, indigestion, colic, etc., resulting in the newborn’s difficulty in falling asleep even if he is sleepy. It is recommended that newborns who are sleepy but find it difficult to fall asleep should be seen as soon as possible for a definitive diagnosis, so as to avoid prolonged insomnia affecting the child’s growth and development.
