My little girl is 13 months now and still breastfeeding, she’s never been a great sleeper up every 2-3 hours for a feed, but just lately the last couple of months she is waking anywhere between 30 minutes and 1.5 hours for milk, she seems quite hungry and feeds for around 15 minutes each time and some nights she will just refuse to go back to sleep for hours. What can I do about this because I am totally exhausted from getting up and down all night long.
