directed or moving toward bed; inclined toward going to bed.
From bed + -ward (from Old English weard, meaning 'direction' or 'toward'). The suffix -ward creates directional adjectives, as in 'forward', 'backward', 'wayward'.
The -ward suffix is ancient and incredibly productive in English—you can add it to almost any noun to show direction, which is why compound words like 'homeward', 'skyward', and 'bedward' all make immediate sense.
