Freaking out!!!

So, it’s 12:30am and I go to feed my baby in the living room. I fiddle with my phone as I try and get comfortable in the chair. Keep myself awake while she eats. I dont remember much, but when I went to my timer to finish the one side, it said that she had been on FOR 46 MINUTES!!! I fell asleep!! I feel horrible! She’s going to be okay, right?? I mean, she seems okay, and still seems like she wants to eat...I feel like a bad mom. :/
