I've got a 7 week old, and just starting to think about structuring her day a little bit to try and foster good sleep habits. The advice on naps seems conflicting though. All the sleep expert websites say that from 8 weeks they should nap in a darkened room in the day to help them produce melatonin and nap well. But nhs/lullaby trust etc say they should be in the same room as you for daytime sleep until 6 months to reduce SIDS risk. So which is it? Obviously I'm not able to sit in a dark bedroom next to my baby for hours each day? I can't find anything online addressing this contradiction so thought I'd ask the citizens of mumsnet...
