...I know this topic has been done to death, but I need more tips please! DS and I are going away this weekend and after my trip a few weeks ago I'm really worried about the cold. I want to cancel 
It was so cold at night I thought I might die. I was snug as a bug under my duvet/bag/blanket combo with hot water bottle but the air in the tent was freezing and my head was frozen despite hat and hoodie up! My face was numb with the cold.
Coldness aside I love camping and this is DS's first trip. He's almost 3 and so excited he could explode. But all I feel is terror at the thought of the night time. I would take a heater but the site doesn't have EHU.
