Sleep

When can I stop waking my 7 week old to feed during the night, she’s a really good sleeper and will sleep through the night if I let her but I’m just so worried about it being a first time mom and what not. The longest she went was almost 8 hours because I set my alarm for pm instead of am to wake her her to eat. Even then I woke up myself and she was still asleep and wasn’t crying but I went ahead and woke her up and she still didn’t cry just kinda looked at me like “really mom I was sleeping🙄”.
