My DD is almost 6 months old. I'm new to this BF thing as I had to FF babies... so I apologize for this stupid question.. here it goes.. a little bit ago my LO was playing on the floor and hit herself in the face with her toy. Immediately started screaming and I picked her up to calm her down. She wouldn't calm down until I nursed her. It hadn't been that long since she ate so I don't think it was because she was hungry. Is that normal/ok?
