Dear smeg thuha5478
Make sure you have a large cotton sheet or a couple of big towels to put down on the sand for her to play on and not directly contact the sand. Vaseline or sorbolene cream are suitable for use as a barrier on the skin before entering salt water. It is also important to wash sand and salt off as soon as possible after contact using a suitable soap free wash/bath oil and then moisturise straight away.
Remember to always try products in a small area first and rinse in clear water immediately if an adverse reaction occurs.
