This ManyMonths body/shirt can make a real difference if…

• your child's clothes quickly become too small, forcing you to constantly buy new ones for a very short period of use;
• you never really know if your child is warm enough… or, conversely, if they are too bundled up;
• you layer clothes, thinking it's never warm enough, to the point that your child is sometimes too encumbered to move freely;
• your child has a fever and wakes up soaked in sweat in cotton clothes, which chills them, disrupts their sleep, and leaves them unnecessarily uncomfortable;
• you would like to reduce the frequency and quantity of laundry;
• you use cloth diapers and classic bodysuits are not really suitable, often forcing you to take a size up, which is otherwise too large;
• you practice or wish to practice Elimination Communication (EC), but classic bodysuits are not practical due to their fixed crotch, while a t-shirt also doesn't offer all the advantages of a bodysuit;
• you have to change the entire bodysuit for a small leak localized only at the bottom of the garment;
• you would like a bodysuit to be worn longer, then continue its life as a t-shirt;
• you are looking for a garment made of natural, ecological, truly healthy material designed for your child's real comfort.

A bodysuit that grows with your child for months… or even two years!

ManyMonths' bestseller for over 20 years!

Baby clothes often become too small in a few weeks.
We accumulate sizes, layers of clothing, laundry… without ever being sure that the child is at the right temperature.

The ManyMonths grow-with-me body/shirt was designed to address these everyday situations.

Thanks to natural merino wool, this garment helps maintain a comfortable microclimate around the child's body: neither too hot nor too cold.

Wool absorbs moisture while remaining warm to the touch. Your child therefore stays dry and comfortable, even when the temperature varies.

An ingenious garment that grows with the child

The ManyMonths body/shirt was designed to be worn much longer than a classic bodysuit.

• Detachable crotch part: the bodysuit then becomes a t-shirt
• Two fastening positions suitable for cloth diapers
• Grow-with-me sleeves that can be rolled up or used as mittens
• Stretchy cut that adapts to the child's growth
• Comfortable head opening (the bodysuit can be put on through the legs)

A garment that accompanies your child well beyond the first months.

Perfect for cloth diapers and EC

This body/shirt is particularly popular with families using:

• cloth diapers
• Elimination Communication (EC)

The detachable crotch allows the garment to be easily adapted to current needs.

And in the event of a small leak, it is not always necessary to change the entire garment or wash it: wool has natural self-cleaning properties. Simple airing of the detachable part is often sufficient.

Exceptional comfort for babies' skin

The body/shirt is made of soft, pure merino wool, in a flexible knit with comfortable seams.

Merino wool:

• naturally regulates body temperature
• allows the skin to breathe
• absorbs moisture while remaining warm
• limits odors thanks to its natural antibacterial properties

It takes about 9 months for a baby's body to learn to regulate its temperature.
Wool can therefore be a valuable aid during this period.

Essential first layer

The ManyMonths bodysuit is the essential first layer, which directly influences the body's thermal balance.

It helps keep the skin dry. Moisture is absorbed by the wool, while the thus dried air can be warmed by body heat and retained by the next layer, for example, a knit or thicker wool.

The first layer is the most important: it is in direct contact with the skin and conditions the entire thermoregulation of the body. It must therefore be natural and breathable.

How to choose the right child size for pre-order (delivery in September)

For pre-orders, you always need to anticipate the child's growth between today and reception. With ManyMonths, it's even simpler:
their sizes are adjustable and cover several classic sizes. This leaves a real margin for growth, without the risk of the garment being too small upon receipt.

Simple rule:

• never skip a size (because you'll be skipping several classic sizes)
• choose at least the next size up
• sometimes the same size the child would wear today - only if they've just started wearing it
