omg this is exactly what I am going through. Mine is 20 weeks and bedtime is 19:30 and stirs and whimpers at 4:00/5:00 almost every night. I have been told that I should put my baby on bed earlier than 7:30 to fix the problem. so she falls asleep at 18:40 today and I'll see what is gonna happen tonight. As for the teething, how can I know her NW is caused by teething or not? I've checked her gum nothing abnormal.
