1hr is pretty long. You can do 20 to 30 mins latch, then pump and keep ur stash. If she demands more milk, you can top up with bottle feed FM/EBM alternate with direct latch. She's drinking quite good but sometimes we can't keep up. Letting baby to latch too long or every 15 to 20 mins though she demand is not good. Your nipple will get blister. My first child demands milk every 15 to 20 mins though during her feeding time she drink pretty good. So I will top up with bottle feed with FM and let her have her pacifier (when needed) This is to also avoid her from being overfed and vomit too. You do the feeding time routine and to ensure she doesn't over feed. You can also do house work easily without getting distrupted.
