Milk night feedings?

When they get switched over to milk from formula at 1 do you give them milk all throughout the night? I have a 11 month old shes slowly starting to eat food but not enough to just survive on. At night what do you do?? She gets up 2-3 times still. Will I just give her milk instead of formula? She wont drink it cold either so do I have to go warm it up every single time? That means if have to go all the way downstairs to get it with a screaming upset tired baby. What do I dooo?!? Help this mama out!! TIA!!
