Laughing during sleep, also called hypnogely, is a relatively common occurrence. It can often be seen in babies, sending parents scrambling to note down baby’s first laughter in the baby book! In general, laughing in your sleep is harmless. In rare instances, it can be a sign of a neurological issue.
Why do newborns smile in their sleep?
Often newborns will smile in their sleep. Sometimes a smile in the early weeks of life is simply a sign that your little bundle is passing gas. But starting between 6 and 8 weeks of life, babies develop a “social smile” — an intentional gesture of warmth meant just for you. This is an important milestone.
When do newborns start cooing?
Babies this age begin smiling regularly at mom and dad, but may need some time to warm up to less familiar people, like grandparents. Babies now discover their ability to vocalize: Soon you’ll have a cooing and gurgling machine! Some babies begin to make some vowel sounds (like “ah-ah” or “ooh-ooh”) at about 2 months.
How many hours should a 10 day old baby sleep?
Newborns should get 14–17 hours of sleep over a 24-hour period, says the National Sleep Foundation. Some newborns may sleep up to 18–19 hours a day. Newborns wake every couple of hours to eat.
