My two children have and do feed all night. I remember that the one who is now 8 was just beginning to improve when he started to get his two year old molar teeth. I know I often slept with him during his daytime sleeps, I was so tired. With my eighteen month old I don't need to make up with sleep during the day but there are nights where she essentially is attached all night. It's certainly worse related to teething or illness (rare) however I've also noticed its worse when I am premenstrual. I don't know if this is actually a change in her behaviour or whether it is because at this time of my cycle I am not sleeping as well and am less tolerant of sucking all night. Anyway, I agree with Kim's recommendations. Jenny Parratt RN RM IBCLC BHlthSc
