How do I choose a crib?
Short answer: Start with safety and fit, then practicalities. Use a mattress made to fit that crib exactly. If it rocks or glides, check there is a lock and use it for sleep where the instructions say to.
- Use a mattress made to fit that crib exactly.
- If it rocks or glides, check there is a lock and use it for sleep where the instructions say to.
- Check the weight and stage limits.
Cribs take up less space than a cot, which helps while your baby shares your room.
What the guidance says
- The NHS advises placing your baby in a separate cot or Moses basket in the same room as you for every sleep, day and night, for at least the first 6 months.
- Use a firm, flat, waterproof mattress in good condition, with no raised or cushioned edges, that fits the cot or Moses basket with no gaps.
- Keep the cot clear: no pillows, duvets, cot bumpers, loose blankets, soft toys, pods, nests, wedges or anything to keep your baby in place.
- Bedside cribs: look for BS EN 1130:2019.
- Mattresses: look for BS 7177:2008+A1:2011, and BS EN 16890:2017+A1:2021 for cot, travel cot and crib mattresses.
