Feeling awful 😭

Me

So I just realized my 10 week old has been nursing in the wrong position for a while now. Most of the time I use the cradle position but he is on his back with his head turned toward my breast. I know now he is always supposed to be laying on his side (belly to belly with me). Now I feel awful because I’m worried he hasn’t been getting enough milk this way or it’s been hurting his neck or something. Just looking for some reassurance or something bc I feel like the worst mom for not realizing that was not a proper position to breastfeed in 😢
