DS has been a great sleeper since we sleep-trained him at 14mo. Happy to go to bed, sleeps all night (normally) and 2-3 hour naps in the afternoon.
But... he has just started waking the night and doesn't want to sleep. He's up. One night it was 12-3am, last night it was up from 3.30am.
He's really getting going on talking right now, so I imagine it might be related to that - but what should I do? Restrict daytime naps I guess?
