Safe sleep guidance can feel like a lot to hold, but it comes down to a few well-evidenced essentials. Learn these, set the room up to make the safe choice the easy one, and you can let go of most of the noise around them.
When in doubt, simpler and clearer is safer.
The hardest moments are the night feeds, when it is tempting to settle your baby wherever you both happen to be. This is exactly why it helps to decide your setup in advance, while you are rested. If there is any chance you might fall asleep while feeding, a clear, safe sleep space within reach makes the safe option the path of least resistance.
For the most current, detailed and trustworthy guidance, including advice on feeding in bed, co-sleeping and what raises or lowers risk, The Lullaby Trust is an excellent, evidence-based resource. It is well worth reading properly before your baby arrives, so the essentials are second nature by the time you need them.
