Since we started sleep training E has pretty consistently gone down for a nap almost exactly 2 hours after he wakes up from his last one. He was giving me his nap signs (eye rubbing, cranky, a particular cry) so I just put him down for his last nap, but he's only been up for an hour since his last one. I'm hoping it will be a short one and won't affect his bedtime too badly. I'd rather have him up a little later than try to keep a cranky baby up now, though.
