I do the last feed after the bath and it works just fine. I think the BW idea is to separate the feed from going to bed, so you're not using the feeding to get them sleepy. But my DS seems to be at his most active just before bed and during this last feed so this isn't an issue for us. If you can do this last feed after the bath without your LO nodding off or nearly nodding off I'd say it's fine - if they do, I'd say it's probably best to feed, bath and bed.
Does that make sense?
