If you think she is distraced during meal times, try to find a place that is quite and less stimulating to nurse. I would turn the tv, and radio off, try to create less visual stimuli and noise. Do you try to settle her at night without feeding? When Claire was that young I would try to soothe her to sleep anytime she woke unless it had been at least three hours since her last feed. If you feed everytime she wakes overnight she will not need those calories during the day and thus starts a vicious cycle.
