Better for baby's delicate skin
Babies have delicate skin, especially premature babies because their dermis - which is the last layer of skin - is not completely formed. Organic cotton is gentle and kinder to a baby's skin.

There is less of a chance of baby developing skin conditions such as eczema, dermatitis and skin allergies. It is mould resistant and antimicrobial too.

Better quality and longer lasting
Because the fibres have not been damaged by chemicals during production, the quality of the cotton is superior. Therefore, clothing made from organic cotton should last longer than those made of conventional cotton.

Better for the planet
For environmentally conscious shoppers there's no doubt that choosing to buy organic cotton clothing is better for the world. Organic cotton farming is less polluting, uses less energy and water, and the health of workers is also not compromised.

So why do we sell non-organic cotton clothing too?
Many of our products are organic, but you do pay a premium for premium products. So to offer a range of value priced items too, we also sell a lot of standard cotton clothing, with no complaints.

It really is down to how sensitive baby's skin is, personal preference, and budget.

Length measurements are from baby's top of head to toe (not length of garment). We very rarely get items from this brand returned.

Baby Girl Sleepsuits

We have lots of baby girl sleepsuits for newborns. These baby girl sleepsuits come in sizes premature, early baby, tiny baby, and 0-3 Months. These onesies are available in traditional pink, but lots of other colours and patterns for baby girls too.

Baby sleepsuits for girls are our most popular item of clothing, so whether buying for a premature baby or a full term newborn you have lots of choice.

Baby girl sleepsuit styles available

Baby sleepsuits for girls normally have poppers all the way down the sleepsuit or part way down, but some come with a zip. Kimono style sleepsuits are popular too. They can be footless or footed, and some come with integrated scratch mitts. For babies on the neonatal ward we recommend the easy-dress design where the sleepsuit can be fully opened, to avoid any stress for baby.
