Advice needed.

My baby is 2 weeks old in 2 days. She will not get off my boob!!! It's getting to the point where she won't fall asleep with out it. She sleeps a good while during the day in her rock n play but at night it is so hard. She won't sleep in her own bed. She has to sleep with me. 😩😩 I love her and cherish these moments while she's so small but I need sleep too. Advice please!!!
