To monitor baby skin development, the investigators will carry out 3 simple procedures at the skin surface that pose no risk to the baby. These procedures will be performed on the arm and thigh, at birth, 4 weeks, and 12 months of age. In addition the investigators will ask parents to answer questionnaires and fill out diaries at specific time points throughout the year, to collect information on how they care for their baby's skin. By recording which babies go on to, and do not, develop eczema the investigators hope to: (1) better understand baby skin development from birth, (2) identify if these simple procedures can predict the development of eczema during the first 12 months of life, and (3) investigate environmental effects that may cause disease onset. In a medical era where the prevention of eczema is the long-term goal, it is hoped that this study will provide a new way to identify babies that may go on to develop eczema. This will allow healthcare professionals to offer specific skin care advice from birth, and empower parents to take measured action to help prevent the emergence of eczema in their baby.
