My little one slept through the night since she was 6 weeks. She would go to bed at 8pm, wakes up for feed between 1 to 2am, and wakes up for another feed at 5 to 6am. She sleeps well during the day too. She is now 14 weeks.

Two days ago, she would be sound asleep and suddenly let out a sharp, loud cry and need to be comforted to bed. During the night, she would do that 4 to 5 times. During the day, she has very short sleep.

Anything happened two days ago? Last week I went away for business trip and came back on Saturday. Yesterday, my helper accidentally cut her finger while trimming her nails.

Any idea what could be the reason? How I can help her?
