Pikolo sizes are done in the European way of measurements rather than age. I found this worked a lot better as children are rarely the size for their age. In my opinion to measure a child is much more accurate & specifically tailored to your child’s growing patterns.

All you need to do is measure your child from head to heel. This gives you a general size. Then if you have a chunkier monkey or want the clothes to last a longer time with turning up cuffs – go a size up. If you’re in the middle go for the true size & If you have a skinny minnie, size down. With organic cotton you always have some shrinkage – this is about 4%. With this in mind we feel after lots of size trials that the majority of the clothes are true to size, with the dungarees running a bit larger. 

They have been designed to give a little extra for cloth bums, but not too much to accommodate all nappy decisions.
