Bonnets, beanies, sun hats and the ones with ears — knitted in organic cotton, merino and cashmere blends. Almost every baby size (0–24 months) has soft ties, knitted beanies included.
Hats for every day of the year
A baby hat earns its place in the first months more than at any other time — keeping warmth in when it's cold and sun off when it isn't.
Ties on the baby sizes. Almost every bonniemob hat from 0–24 months has soft ties, and that includes the knitted beanies, not only the bonnets. It's a small piece of construction that will save many hours searching for a hat lost in a crib or stroller. It's what keeps a hat sitting where it should.
Natural fibres throughout. GOTS certified organic cotton, merino wool, or organic cotton blended with cashmere. Merino deserves singling out: the fibre is fine enough to sit softly against new skin, and it moves moisture rather than holding it, so it stays warm and comfortable through damp weather. Organic cotton is the cooler, lighter choice when the weather is warm. Both are lovely against delicate skin.
Lightweight jersey beanies are soft, unlined and stretchy — easy indoors as well as out. The knitted and lined styles are the ones for outside.
A hat makes a lovely small baby gift. Beautiful to unwrap, and useful from the first week. A hat with a pair of knitted booties, or with a muslin or teether makes a complete gift at a lower price.
Finding the right size. Hats are sized by age, but head size varies between babies more than age alone suggests. The size chart shows how to measure — a soft tape around the widest part of the head, just above the ears and eyebrows — so you can match the measurement to the right age size.
Organic baby hats, infant bonnets, newborn hats, beanies, hats with ears, baby turbans and childrens sun hats, from newborn to nine years.
FAQ's
How do I measure my baby's head for a hat?
Run a soft tape around the widest part of the head, level, just above the eyebrows and the tops of the ears. Match that measurement to our size chart to find the right age size. Between two sizes, take the larger.
Do the knitted beanies have ties?
Yes — almost every bonniemob infant hat in the baby sizes (0–24 months) has soft ties, knitted baby beanies included.
Can my baby wear a hat indoors?
The lightweight jersey beanies are made for it — soft, unlined and stretchy, so they're comfortable in a cool room. The knitted and lined styles are better kept for outdoors.
Are the baby hats wool or acrylic?
Natural fibres only here at the bonniemob — GOTS certified organic cotton, merino wool, or a cotton and cashmere blend. Nothing here is acrylic, which is a plastic yarn that holds warmth and moisture against the skin rather than letting it evaporate naturally.
Is merino wool soft enough for a baby?
Yes. Merino fibres are far finer than standard wool, and fineness is what makes a yarn soft — they bend against the skin rather than pressing into it. Merino and organic cotton simply suit different days: cotton is cool and light for warm weather, merino is warm and comfortable through damp British winters. Both are lovely against new skin.
How do I wash a baby hat or bonnet?
Machine wash at 30 on a wool or delicate cycle, ease back into shape and dry flat. We don't recommend tumble drying: heat and tumbling shrink and felt knitted fibres, soften the elastic that gives a hat its grip, and lift the surface so colour dulls. Dried flat, a knitted hat holds its shape and its colour for years.
Let customers speak for us
from 1104 reviewsJust discovered this shop and love the attention to detail and care that goes into the clothes. I ordered some baby cashmere in the sale and am really impressed with quality and value.
Adorable soft jumper. Very pleased with the quality and the design is so sweet. I would size up if in doubt, my son is 5 months and the 6-9 month fits well.
Beautifully made dress, so pretty but also comfy and practical and perfect for in-between weather! My daughter loves it.
Beautiful feel to this bodysuit and the design is exactly what you'd expect from the brilliant Bonnie Mob!
Lovely clothes
Loved these shorts last summer so bought size up this year, little one was delighted when they arrived and wanted to wear them right away. Comfy and she loves the pockets and bright pink colour. Super cheerful
EXCELLENT

I shopped at thebonniemob with ease and love the products.
Very happy with this lovely cardigan for my granddaughter.
A gorgeous little coat. It’s an excellent fit and very cosy.
The sweetest little dress. My granddaughter loves it and it’s beautifully cut and well made.
I’m really impressed with the baby clothes I bought from Bonnie Mob! The organic cotton feels incredibly soft and gentle on my baby’s skin — you can truly feel the quality the moment you touch it. The fabric is well-made and durable, even after a few washes, and the designs are absolutely adorable. You can tell the difference compared to many other brands — Bonnie Mob clothes just feel more premium, comfortable, and thoughtfully made. Definitely one of my new favourites for babywear! 👶💛
Adorable! Looks small
Love it!
