I have a dd who is nearly 3 weeks old. 2/3 hourly breastfeeding and lack of sleep is draining me already. I need to know that there is a light at the end of this tunnel and was wondering if someone could tell me how long before she gets to feed 4 hourly. My dd is also asleep alot of the time during the day and awake at night when will her sleeping pattern change so she will sleep more at night?
