What is the easiest way to tell if I'm having supply issues? I'm doing weight watchers, DD is teething, and she seems to be eating more frequently. She went from eating every 3 hours, to eating every 1.5 to 2 hours. Plus, she has always only nursed from one side, now she is starting to nurse from both sides. Is it because she is hungry, or could it be the teething? Thanks!
