Baby bedding
For the first few months, you'll need a crib, carrycot or Moses basket (a light, portable bassinet). Your baby needs to sleep somewhere that's safe, warm and not too far from you.
Baby nests are not suitable for your baby to sleep in when you're not there because of the danger of suffocation.
If you're borrowing a crib or a cot, or using one that's been used by another of your children, you should ideally buy a new mattress.
If you can't do this, use the cot mattress you have, as long as it's firm (not soft), flat, fits the cot with no gaps, is clean, and waterproof.
You'll need:
a firm mattress that fits the cot snugly without leaving spaces round the edges so your baby can't trap their head and suffocate
sheets to cover the mattress – you need at least 4 because they need to be changed often; fitted sheets make life easier but can be quite expensive, so you could use pieces of old sheet
light blankets for warmth
Pillows and duvets
Don't use pillows and duvets – they're not safe for babies less than a year old because of the risk of suffocation. Duvets can also make your baby too hot.
Sheets and layers of blankets tucked in firmly below your baby's shoulder level or a baby sleeping bag are safe for your baby to sleep in.
Cot safety
Your baby will spend many hours in a cot, so make sure it's safe. If you're buying a new cot, look for the British Standard mark BS EN 716-1.
The mattress must fit snugly, with no space for the baby's head to get stuck.
The bars must be smooth, securely fixed, and the distance between each bar should not be less than 25mm (1 inch) and not more than 60mm (2.5 inches), so your baby's head can't get trapped.
The cot should be sturdy.
The moving parts should work smoothly and not allow fingers or clothing to get trapped.
Cot bumpers are not recommended as babies can overheat or get tangled in the fastenings.
Never leave anything with ties, such as bibs or clothes, in the cot as they might get caught around your baby's neck.
The safest place for your baby to sleep is on their back in a cot in the same room as you for the first 6 months.
