I don't know about B&Bs but I am sure they will let you use their fridge in their kitchen. At that time of year you could even try keeping the milk outside!
The hotel we stayed in in Oxford had no fridge in the room. It was a third floor walk-up and we had no access to the kitchen. Actually, the hotel we frequent in London has no fridges in rooms either.
That said, your kid doesn't need milk, unless it is a cow. It will be fine.
