1. Should it be "after" instead?
2. Is the comma after "bed" needed?
Thanks.
_________________
1. "After" is the correct choice.
2. Comma is required after "bed". In its absence, the middle part will be "... bed before Tay ...".It conveys the sense "bed in front of Tay". A comma makes the sentence clear.
