Tips on stopping breastfeeding?!? HELP

My girl is going on 15 months old. She nurses once she wakes up and a bit after she eats breakfast. Then we’ll get ready, start our day and she’ll play for about an hour or two and nurse again, wether it’s for 1 minute or 10 minutes. And so on and so on. The most she nurses during the day (including from when she wakes up) is about 6 times or less. Then bedtime rolls around and she nurses herself to sleep. As long as I’m around she can’t fall asleep without the boob. If it’s just her and her father she’ll fall asleep without it no problem. She’ll wake up once or twice during the night to nurse.

So... I need a lot of advice on how to get her to slow down, and then eventually stop all together. I would looooove to get a night to myself and my hubs without getting a call that we won’t stop screaming for my boob.
