wee (wē), adj., we•er, we•est.

little;
very small.
very early:in the wee hours of the morning.

As sdgraham points out in The use of the word "wee" - the entry is misleading.

I suggest an entry

Phrase: "the wee hours" - 'the small hours' very early in the morning, usually between midnight and 4 a.m

There should also be a corresponding entry for "the small hours".
