Yeah I think for now we are getting the tacking because the nap is just being cut, it's early stages for us. What often happens is that because he's always so ahead of himself with these transitions, he 'catches up' with his A times or less sleep and then he'll stop tacking and it's a sign to tweak. So far the tacking has only been him going back to sleep, he doesn't sleep straight through. He'll still wake, make noises or sighs at his 5:30/6 wake time but then he'll drop back off, sometimes for an hour, sometimes less. If we were to put him to bed too early, we would get a much earlier waking, I'm sure of it. This morning he cried out a bit just after 6 but then didn't hear him proper until 6:40ish - and that was on the back of a 7:30 bedtime. While we have some nap at all, we have to juggle bedtime accordingly to prevent OT but also to prevent a too early waking. Ack!
