Supply ?

PrncesWife

DD was eating really well until about Monday.  She was averaging 10 minutes per side, every 2-3 hours.  Monday hit and it became a struggle to get her to eat 5 minutes per side.  Now whenever she eats for more than 10 minutes total she spits what looks like everything back up.  Up until today it was white and chunky, today it was yellow.  I called the nurse, and I think when we go in to our appointment tomorrow they will diagnose her with reflux.  So lately she seems to do better just eating on one side at a time.  While this means she is eating a smaller amount, therefore needing to eat more frequently, I am ok with that.  What I am wondering is what it will do to my supply.  Is is better to have her eat 5 minutes per side (in terms of my supply) or will we be ok if she eats 10 minutes on one side per feeding, alternating sides each time?
