My newborn is 17 days old. Last night, they didn’t take a nap, and this morning they only slept for a few minutes before waking up unwillingly. They vomited shortly after feeding, which might be due to indigestion or improper feeding. It’s recommended to adopt the correct feeding position and to hold your baby properly after feeding to reduce the occurrence of vomiting. These are suggestions for the issue of ‘My newborn is 17 days old and didn’t sleep last night.’ I hope this helps you, and wish you health!
