So the last couple days my daughter has been maybe breastfeeding on one side (this is all during the day) and not even finishing it. I've been having to pump and give her her sippy cup where she'll drink it all. I know she's hungry but it's frustrating when she will literally just unlatch and either lay on my boob or decide to look around. She has always eating every 3-3.5 hours and still bf at night with no issues! Any ideas of what's going on? No sign of any teeth!
