breastfeeding mommy nutrition

Hello! Any new moms out there struggle with eating enough throughout the day? Don't get me wrong, I'm so hungry all the time, I just never have enough time to be able to grab something for breakfast lunch and dinner. I end up eating lunch around 2 and then dinner shortly after and that's all I end up eating all day. I'm worried for my baby because he's probably not getting enough/ the right nutrients from me. Help!
