DDP PACE training
DDP PACE training provides you with a thorough understanding and experience of PACE embedded within the DDP framework.
PACE stands for playfulness, acceptance, curiosity and empathy. This training explores the PACE attitude, a way of thinking, feeling, communicating and behaving that aims to support the child to feel safe.
We recommend this training to individuals and organisations where DDP Level One training may not be appropriate for their circumstances. It may also be helpful for people before they attend a DDP Level One.
DDP PACE training is open to everyone. It can be especially useful for people working with, or looking after, children with developmental trauma that show attachment and relationship difficulties with their primary caregivers. This includes all professionals, parents and carers.
