My 12-week-old daughter has practically refused to nap during last two days. She is unusually agitated and wants to suck almost all the time. Is something wrong with her?
11-13 weeks is when a growth spurt may take place. 11-13 weeks is also the time when yet another wonder week may occur.
The slightly-fussier period of a wonder week may last for a few weeks.
The extremely-fussy, constantly sucking no-sleep growth spurt period usually lasts only 2 or 3 days.
If you are really worried or seeing another worrysome symptom, don't hesitate to consult your pediatrician.
