Hi everyone. Miraclelim - I agree - try a later, capped nap. Hope that sorts it for you. Sleep is precious when you've got a really little one too.
Not sure what's going on with us. Jack is doing 2 NNDs a week at nursery, though randomly napped one of those days this week and we've had funny / short nights since. We've been capping at 45 minutes at home for a couple of weeks and it's worked really well, but he was also ill during this time. Part of me thinks he slept better cos he was ill and now he's better he needs less sleep. That's happened with us before, and my daughter was the same.
Anyway, rambling a bit. He's also turning 2 in a couple of weeks so I'm aware it could be developmental too. I'm resisting the urge to tweak right now....
