Improper latch-on can cause pain and really interfere with breastfeeding. Here is a walk-through on proper latch straight from my own lactation consultant, Elisa Hirsch, RN, BSN, IBCLC.
Position your baby with her body facing yours and with her nose
Stay hydrated (keep a water bottle within reach while nursing).
Eat a balanced diet (about 500 calories more than you ate before pregnancy…yummy!).
Breastfeed regularly.
Pump it up (pump an extra morning feed if you have time).
Get enough
