I hate to sound all "Bah Humbug" but my 5mo DD's daytime sleep routine has been destroyed by the disruption to her (very loose) routine over the Christmas break. She would usually have about an hour in the morning, two hours at lunch (usually in the pram) and then a catnap at around 4:30. Now I'm lucky to get her to sleep for longer than an hour all day. She's an overtired mess and just whinges all day. I've had so many unhelpful comments from visiting relatives which just gives me unbelievable rage. 
Anyone else experienced this and will I ever get my napping baby back?!
