Newborns often make noises and struggle when falling asleep at night, which may be a sign of hunger or the need to urinate or defecate.

Lately, the baby has been experiencing a sudden jump reflex during naptime, stretching and twisting, leading to restless sleep and frequent waking up, with each sleep session lasting only 5-10 minutes. This is a deviation from their previous sleep pattern. Previously, the baby could sleep for 1-2 hours during the day and 3-5 hours consecutively at night, but now the daytime sleep has been shortened to 5-10 minutes, and nighttime sleep to about 1 hour. The baby had hemolytic jaundice and received blue light therapy, after which the skin developed rashes, and the baby was also more restless while breastfeeding.

A 7-month-old baby experiences unstable sleep at night, turning over every hour with slight crying sounds. This may be due to insufficient nutrition or a lack of trace elements, and it is recommended to conduct tests and adjust the diet.

A 4-month-old baby often wakes up during afternoon naps at night, which might be due to a calcium deficiency.
