Help! My usually gorgeous boy has turned into an unsettled, feeding, non sleeping nightmare! For the last few weeks he was sleeping from around 7 to 1:30 and then to 5 and now he is waking at 12, 3, 6 and so on. He is 11 weeks old and this has been going on for the last 5 days. He isn't usually whingy and doesn't cry a lot but lately he is so fussy. Is anyone else going through this and does anyone know how long these "growth spurts" last? I'm walking around with the biggest bags under my eyes and am losing confidence in myself!!!
