Toddler Nursing ALL the time

Gracie

My 2 year old still nurses but the last 2 weeks he's been nursing sooo much more and gets so upset when I tell him no and offer milk or water. He was transitioning well at night where we would nurse and then I'd lay him down and he'd go to sleep. Past few nights he sits right up and refuses to sleep without me nursing him in his bed. Loosing some sanity over here haha any suggestions or ideas why he's nursing so much?? Thank you!!
