Is my 1 year old done with the boob??

Last couple days she doesnt want it when she wakes.

I dream feed her some if possible on her morning nap.

Then before bed last 2 or possibly 3 hasn't wanted it.

But im confused as the last few days shes been up nearly 2.5 hours I'm super tired!!!!!

Normally she might go 3.5,4,5 hours.

She's taking milk In the night but I don't know if thatabjust comfort or routine or if I should stop so we both get sleep but same time I've been letting her feed as I keep thinking it's her immune system it's helping.
