Hedgehogs

Hi

I have a baby hedgehog in my garden I am feeding him every night he comes out about 5.30pm for about 6 hours or until the food is gon

We think he is nesting under our shed

Is there anything I can do to help him get through the winter 

We have a hedgehog house this is what I put the food in every day as there are cats on the garden early in the mornings 

Can any one give me advice on food or bedding I can put out for him please
