At each appointment, your midwife will check baby over, looking at their physical condition and behaviour. Some babies develop jaundice. This is a yellow tinge to the skin and eyes. This can be completely normal as baby adjusts to independent life. In some cases, it can be more prominent, and baby needs treatment under UV light.
Your midwife will also ask about wet nappies, poo nappies, feeding and she may offer to weight baby. All of these checks are to ensure your baby is adapting and thriving; any problems can be detected early, and a plan made to rectify them.
