Has anyone else been so exhausted that they didn’t wake up to their baby crying really hard.

So today I️ woke up to my mom shaking me, trying to get me to wake up. I️ look at her and my screaming baby is in her hands. She asks me why I️ didn’t get up with her and tend to her when she started crying. I️ reply with that I️ literally did not hear anything. I️ was in such a deep sleep. Now, as I’m sitting here feeding my child, I️ can’t help but cry knowing my baby girl was crying cause she was so hungry and she needed me and I️ didn’t even hear her. Like what if she were hurt? Now mind you, ever since having her I️ am the lightest sleeper. She makes one little noise and I’m instantly awake. She coughs a little and I️ jump out of bed to check on her. I️ feel like such a shit mom. Has anyone else done this once or twice. If so how did you feel about it.. am I️ being too much for thinking I’m a shit mom. I️ suppose it could be the pp hormones but it’s how I️ feel.

Edit: my mom was actually being nice she was just confused
