Pregnant and nursing

I just found out I'm pregnant again. We are thrilled and it was planned. However, when I conceived my second kiddo (January baby), my first had already weaned from nursing. My nipples are super sensitive right now and nursing is so painful. Baby has 4 teeth now. Every time she latches it feels like I'm nursing a shark. At first I thought she was biting me, but she isn't.

Anyone else been through this? Tips and advice? I'd like to nurse her as long as possible, as she had some health issues a few months back. She doesn't take a bottle. 😬
