Baby boy clothes, made to last

Prints with some character to them. Bananas, stars, checkerboards, dinosaurs and rainbow stripe, hand-drawn in Brighton since 2005. Olive, ginger, sky, navy and sunshine — colours chosen because they are good to look at, and because they photograph beautifully on a small person.

Fully fashioned knitwear. Cardigans, jumpers and dungarees knitted panel by panel on the machine rather than cut from a sheet, so there are no offcuts and no raw edges inside. Turn-back cuffs let the sleeves down as he grows.

Organic cotton, washed at 30. Everything is machine washable, cashmere blends included, on a wool or delicate cycle. Never hotter than 30. Made to be durable, washed often and handed on.

An easy gift. Boxed gift sets, personalised blankets, or build your own gift box and choose the pieces yourself. A handwritten card can be added at checkout.

Sizes run by age, newborn to nine to ten years. The size guide gives the height each size is cut to, which is the surer way to choose.

Baby boy clothes and baby boy gifts in organic cotton — sleepsuits, rompers, dungarees, cardigans, knitted blankets and boxed gift sets from the bonnie mob.

FAQ's

What sizes do you do?

Newborn through to nine to ten years. Sizes are labelled by age, and the size guide gives the height each one is cut to — checking height is the surer way to choose.

What makes a good baby boy gift?

A knitted blanket is the one that gets kept. Personalised blankets are knitted with a name, and there are boxed gift sets, or you can build your own gift box and choose the pieces yourself.

Is the cotton organic?

Yes. The range is made with organic cotton.

Can I machine wash it?

Yes, all of it, including the cashmere blends. Wool or delicate cycle at 30, and never hotter than 30.

How do sleepsuits fasten?

With poppers or a zip, neck to ankle, depending on the style.

Are the clothes unisex?

Most of the range is designed to suit any child. There is a unisex collection if you would rather browse that way, and it is the easiest place to start when you are buying before a baby arrives.

Just 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.

Mushroom Fleece Baby & Kids Organic Dress

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! 👶💛
