c. Factors to consider when selecting a baby’s clothes; the clothes must be warm as the heat regulating mechanism of a young baby does not function properly in the ﬁrst few months; the fabric used must be soft and nonstick to prevent soreness and irritation; the fabrics used must be light in weight as the heavy ones make the baby uncomfortable; clothes should be large enough to allow for some growth and free movement of the baby; clothes should be of simple style and pattem for easier wearing and washing; 1 light,warm or bright colours are best as they look cheerful and attractive; clothes should be easy to wash since they get dirty quickly and need constant laundering; ‘ clothes should be easy to put on and remove therefore should have tie tapes; clothes should be non-ﬂammable to keep baby safe from ﬁre; should be strong to withstand frequent washing.
