Hi, has anyone got any ideas how i can drop my 14 month olds last breast feed. We have got down to just this last one and she happily drinks cows milk during the day. However, last night i offered her her sippy cup with cows milk rather than the boob and she wasn't having a bar of it and cried with such genuine upset i gave in and gave her a breast feed. Also is it normal that at 14months she is still waking for that 5am feed? She sleeps from 7-7 with that one wake usually and am beginning to wonder if she will ever give me an unbroken nights sleep, as all my friends babies seem to have slept through from a very early age.
