Bedding essentials before your baby arrives

There are countless pieces of baby bedding available to buy,  but you don’t actually need that much to keep your baby comfortable when sleeping – although you might want to have a small stash of the basics ready for when mishaps happen. 

Before your baby arrives, it makes sense to stock up on some basic baby bedding. Go for a minimum of:

  • Three bottom sheets
  • Three top sheets
  • Three blankets.

You'll more than likely get blankets as presents, but it's always useful to have a few extra.

Baby sheets

Fitted sheets

These are very useful, especially as your baby gets older and moves around in the cot more. A fitted sheet won’t ruffle and come away from the mattress as a result of a squirming baby. However, they can be tricky to fit if the cot mattress you've bought is quite stiff and heavy.

Fitted sheets tend to be made of cotton jersey or terry (fine towelling cotton/polyester mix), which won't require ironing.

Flat sheets

These tend to be used as a top sheet in combination with a blanket. They're fine for use as a bottom sheet too, but are generally more awkward to put on than fitted sheets.

Flat sheets tend to be made either from flannelette or plain cotton. Plain cotton has the advantage that it can be washed at higher temperatures, although it doesn’t feel as soft as flannelette.

Baby blankets

The types of blankets most commonly available are cotton cellular, acrylic cellular and fleece.

Cotton cellular blankets

The cellular structure of these 100% cotton blankets mean they're warm in winter and cool in summer. They're also lightweight, and are washable at higher temperatures than fleece or acrylic.

Acrylic cellular blankets

These are extra-lightweight and quick drying, with the same year-round usefulness as the cotton cellular type. They're similar in price to cotton cellular blankets, but tend not to be as soft on the skin as cotton or fleece.

Fleece blankets

These are made from 100% polyester, are soft for your baby and easy to wash and dry. They tend to be more expensive than other types, though.

Baby coverlets and comforters

A coverlet or comforter is a lightweight baby bedding version of a quilt that can safely be used for babies under one year old because it doesn't have the soft padding of a standard quilt. It's as warm as a sheet and blanket combined.

Always follow the manufacturer's instructions before using a coverlet, as some aren't suitable for babies under 3.5kg or 7lb 12oz.

Baby sheepskin fleeces

These are basically mini sheepskin rugs. They're designed to be soft and comforting for babies to lie on, and many parents feel they calm and soothe newborns. If you buy one, make sure it's specifically for baby use.

Quilts, duvets and pillows safety advice

Quilts, duvets and pillows shouldn't be used for babies under one year old. 

After this, it's fine to replace baby blankets and top sheets with a cot quilt or duvet if you wish. For toddlers, we recommend starting off with a light 3–4.5 tog before moving up to a higher tog as they grow. make sure they still have access to a blanket, so they can regulate their own temperature if needed. 

Avoid using a 10.5 tog or higher until your child is aged 10.

Pillows can also be safely used from the age of one year, but don’t feel you have to buy one – your baby will be used to sleeping without one and may even not want it in the cot.

Baby sleeping bags

Sleeping bags designed for babies and young children usually have a full-length front zip or poppers at the shoulders, and sometimes a zip at the side with sleeveless arm holes. Rather than tucking your baby up at night under sheets and blankets, you simply zip or popper them into the bag.

According to The Lullaby Trust, sleeping bags should be cotton, lightweight and not have a hood. Make sure the sleeping bag is not too big around the neck, to prevent your baby from slipping down into the bag.

There are no covers to throw off, so your baby stays warm all night. However, older babies and toddlers may find the bags constricting.

Cot bumpers

These are soft pads that are tied to the sides of the cot, designed to give babies some protection from the hard sides. However, they definitely sit under the 'optional accessory' category. If you do buy one, it should carry BSI number BS 1877-10:1997.
