can anyone advise what's going on? my nearly 4 month old boy has started waking frequently in the niht having previosuly been a pretty good sleeper. we'd only had a handful of nights where he didn't wake at all, but he was really only waking once or twice. for the last week he's been up to about 7-10, all after 2.30ish. he still oes down well at 7 generally waking only once before 2.30ish, except when i give him his 11 o'clock feed. i am knackered and confused. any ideas what's going on and how i stop it continuing or becoming a habit?
