Momma milk?

Just a day shy of three weeks without nursing, E asked to nurse and wouldn't let it go. He never became angry or frustrated when I'd try to distract him, he'd just continue to ask and smile at me. I finally agreed and I asked if he remembered how. He said that he did and was so excited to nurse. He latched on and drank for about 30 seconds, if that. He was content with what he taken and was off and playing again.
