Louis has also turned into a nightmare in the last 2 weeks, gone from being a happy sunny little boy who was always helpful to lots of 'no's' and paddys, and hitting us and Josh, it's horrid! I'm exhausted and ended up quite down since new year so please don't think you are alone and it could well just be an age thing as well as the disruption over xmas. I remember Josh doing the same sort of thing and lots of others on my bc board at the time being in the same boat. Sorry I know it is not much help (now 9.10 here and he is still awake )but you are not alone!
