My DD in 7 months and still wakes 2-3 times a night. I feed her as she is then back asleep within 15 mins whereas when I try and settle her she just cries till she gets fed. I don't think my DD is hungry at all- just looking for mummy and comfort in the night. This is very common and normal. Sleeping through is usually a 5 to 6 hour block, not from 7pm to 7am (as I initially thought). I just gave up and now try to structure my days so I get rest during the day and a sleep when she has a nap. I am too tired during the night to try settling. Give it a go if you want. I have found over time that her time between waking has stretched bit by bit. Is taking her in your bed an option?
