Assess her needs first (rule out feeding, changing, etc) and then do what's best for her personality and for your sanity and family situation. My daughter (when about 7 months old) was stubborn and we were falling apart from getting no sleep so we ended up doing cold-turkey cry it out (if we went in, it made it FAR worse) It took 3 days- first night, she cried 45 minutes. Second night, she cried 15 minutes, Third night, she whimpered for a few seconds and then put herself fast to sleep. We haven't had issues since then and she's 2 and a half. It was the hardest thing I ever had to do but it gave her the MOST important gift- being able to put herself to sleep and soothe herself if she woke up. That's the key. So I recommend, checking to make sure she's okay and then letting her fall asleep on her own. Don't rock or nurse her to sleep or you train her into needing that. Decide what's right for YOU and stick to it!
