When buying clothes for newborns there are important things to consider especially if the baby is a tiny preemie baby.
Important things to consider when choosing baby wear are softness of fabric and fit. These are even more important when the outfit is being purchased for a small newborn baby.
A baby that is being cared for by nurses because of its size will need to be wearing clothes that allow the medical staff easy access when they need to do the routine checks.
Hats might be needed for the infant, these need to be soft on the skin. Size wise the hat needs to be small enough to stay in place but loose enough to be comfortable and easily removed. A hat may also need to allow access for monitoring the temperature and also to allow access to any tubes the baby needs at this stage. If you are unsure about the suitability of garments for the baby it is a good idea to seek advice from the hospital staff.
