Premature or tiny babies are unable to keep themselves
sufficiently warm. They are also very weak and prone to
infections. An incubator is a special type of a cot which
provides an ideal environment for the baby. It tries to
stimulate the condiditons as inside the womb.
Some incubators have open tops but even if they don't,
they have holes at the sides through which you can touch
and stroke your baby. Needy babies are placed in incubators
till they are stronger.
