When your child needs to have an Ultrasound to look at their tummy, head, heart or any lumps or bumps, it can be helpful to prepare them through pretend play. This video by the What? Why? Children in Hospital charity shows how you could play with your child the day or morning before you go to hospital. Mum and Aidan use a strawberry jelly to play pretend Ultrasound. This video with pretend hospital play is aimed at younger children and those at an early stage of development.
