Transitioning from Breast to Bottle at 9 months.. HELP

Raven

I just found out I am pregnant again and my breastmilk is starting to dry up which is bad for my 9 month old daughter who has always refused to take anything but the breast since birth basically. She has lost a pound in the last month due to it and is up all night because she isnt getting enough so I need tips on how to get the most stubborn breastfed baby to transition to a bottle/sippy/360 cup ANYTHING!!! Her health is depending on it, poor baby ❤
