We have learned a guy who lives in our close gets up and leaves for work between 5 and 5.15 - on his very, very noisy motorbike
No wonder Maximus is always wide awake by 5.30.
At least when the weather gets colder he will go back to using his car so we might get a bit of a lie in then.
Also we are extremely lucky as once Max has got up and done his business, he happily goes back into his crate and goes back to sleep.
Not bad for almost 6 months old.
