Night feedings?

Al

Anyone still feeding in the middle of the night? I never sleep trained my 14 month old so he usually wakes in the middle of the night. I just nurse him and go back to bed. This is our only nursing session these days. We co sleep. I want to be done with nursing but don't want cut him off cold turkey. I was thinking about having a bottle of milk in beginning instead of my boob but don't want to go downstairs at 1am to make it. Two questions- is this a good way to wean him off the last nursing session? And if so how can I keep his milk bottle at the right temperature in my bedroom? Wound a cooler be sufficient or do I need a legit fridge?
