Everyone tends to breathe a sigh of relief when the warmer weather comes around. Winter sickness fades away, the sun is shining and you emerge from you hibernation cocoon.
Parents can tend to stress how much to cover up their babes. In Winter it's easy... layers up on layers so they stay rugged up and warm. In Summer though, it can be hard not to stress we are keeping them too warm.
Remember the general rule of thumb us a baby needs an extra layer than us. Muslins are a great choice for the warmer months. They're light enough to not overhear them but still offer a layer against the elements and to protect their delicate skin to a degree - remember to apply relevant skin protection against the Sun still though.
