My dd is 16 weeks and i have been breastfeeding her exclusively apart from a bottle i started giving her late at night in an attempt to get her sleeping better - this has worked well and the bottle was introduced about 6 weeks ago, so why has my milk gone? dd try feeding and within seconds she is squirming around and yelling her head off! i have tried on both sides and she does the same, i have tried hand expressing and with an isis pump and there is NOTHING there!! how is this possible? i havent done anything differently! i have tried persistently feeding her but she just does the same thing! im really confused by this, please can anyone help???
