I have a 13 day old daughter who is breastfed but I often 'top up' one feed at night with <1oz formula to get some sleep. She feeds for two hours at a go sometimes more and just seems to never be satisfied by breast milk alone at night (fine in the daytime). I really want to persevere with b/f but there are only so many hours at night in which to sleep and she would have me feed for all of them. I am concerned about coping in the day with dd1 when dh goes back to work next week. Can anyone tell me what to expect with bf at night?...When will the cluster feeding end? How long can I expect each feed to take when the dust has settled and how frequent will they be? Thanks in advance for any advice.
