My ds1 has always had a fairly good sleep pattern, going to bed at 7pm, waking at around 2-3am for a feed and then going back to sleep until 6.30am ish. In the past couple of weeks he has started waking constantly during the night, at 10pm, 12midnight, 2ish (when I feed him), 5am. I tried offering a feed but he's not interested, tried cooled boiled water, dummy, checked for teething, he's not ill and he's just wide awake and crying. I can't understand why he's suddenly started doing this, especially as it's been two weeks now rather than just an odd couple of nights. It means he's not getting good long sleep, which I presume he needs, and I'm not either...and I know I need it! Any suggestions as to why this might be and how I might resolve it?
