My dd at around 8 weeks would sleep from 10pm-6am and has even slept 10-9am a few times, but the past week she has started waking in the night the past few it's been every 2-3 hours and the only thing that will stop her screaming is feeding her. As she has been able to go through the night without should I be feeding her? I have a 2yr old too so I'm conscious bout her waking her if she screams for so long. Anyone have any hints or tips to try? I can't see a light at the end of tunnel at the mo..
