So my daughter is 9 weeks old and will sleep through the night and lets us know when she’s hungry etc... I went to her weigh in and she’s under weight but only by 7 ounces so not a big deal. But my mom friends are telling me that I’m being irresponsible by not waking her up to feed her.

Do you wake your babies up to feed in the night if they don’t wake themselves? I’m scared I’ll be creating a bad habit if I start waking her up and breaking her if the habit of sleeping through the night.
