I'm up when DGS age 3 decides I should be!
Family are staying with me while their new house is being completed, and the young chap is a VERY early riser.
I usually get a pile of Dinky cars poured onto my pillow around 5am, and a little voice says: "Nanny, get up, you need a nice cup of tea!"
He's right, I definitely need a nice cup of tea, but a couple of hours later would be even nicer!
I dont really mind, because like many other Gransnetters I have chronic pain from arthritis, and I definitely have a better day if I rise early and have my medication and a hot shower.
He never gives up being stupid.

Love my bed.
I'm more than happy to stay up until the wee small hours, but I don't sleep well, and therefore I hate getting up early! The only problem is that DH is also a 'Night Owl', but he still gets up with the 'Larks', and constantly complains that I'm wasting the day away if I don't get up early! I can see his point, and wish I was one of these people who could get up early, feeling refreshed!
