I hope somone can help. My 4wk old dd is very sleepy all day, falling asleep on her bottle and not staying up to play on her mat etc, then very alert in evening, which is fine but then becomes overtired, last few nights has been awake from 5 til 10.30 or 11 and very ratty and crying the whole time. She sleeps at night from 10.30/11 to around 3 then again til around 7. I don't feel these fraught evenings are doing anyone any good and feel she should be awake more during the day instead of just one long nap punctuated with feeds which she falls asleep from.
