I don't have to wake DD to eat anymore, but I feel like she's going too long between feedings. She's BF, and even though I was told I don't have to, I still try to stir her every 3 hours to eat. I'm afraid if I don't, she'll either wake more to eat at night, or just not get enough to eat during the day. But if she's napping, she'll easily go 4+ hours sometimes. Should I just trust her and let her be? I know it's important for her to get her sleep too. I have no idea how much she's eating when she nurses.
