The Egmao Wrap Baby Wrap is designed with just the right amount of elasticity, conforming perfectly to your body with no need for constant readjusting unlike less elastic baby wraps. When using the Egmao Wrap to carry your newborn, toddler or even a preemie, the closeness and lull of your heartbeat will settle and calm your baby. The Egmao Wrap is a little shorter in length than some other brands but it will fit most any physique with the 5% Spandex French Terry mix. You may choose to tie the knot in front, in the back or on the side, depending on how much slack you have. On the side or in front will make sitting down in the wrap more comfortable as the knot will not be in your back. Each time you tie your wrap, you are creating a custom, ergonomic fit for your baby and the X that forms the seat grows with your child. Did you know that infants can't thermoregulate? This means that they just can't deal with being hot or cold the way that we adults do. Their internal furnace or cooling system (think, sweat) is not fully formed yet and so they rely on your body for that! You'll notice that when you wear your baby close, you will heat up or sweat more than usual. That is your baby using you to thermoregulate! That's just one of the many benefits to your baby that Egmao Wrap facilitates. It also supports a healthy immune system, with less ear infections, less crying (43% less!) and more sleep. So we called it the Egmao Wrap and we've been delivering these benefits for over 10 years.
