My newborn (about 4 weeks old now) takes hours to feed - this has been the case since birth. When breastfeeding, she can feed for 3, 4 even more hours and then still be hungry when removed from the breast. We have started topping up with formula after 1 hour of breastfeeding and she can still take an hour and a half to finish the bottle making the feed take two hours or more in total. To clarify, she is constantly sucking during this time, not falling asleep or taking breaks, or sucking gently - she is constantly taking milk for the full time. Getting her undressed/skin on skin doesn't make any difference.
Is this normal? Is there anything we can do to make her eat faster - my wife is slowly losing her mind!
