Daniel Siegel, MD discusses the importance of presence, attunement, resonance, and trust in developing attachment between children and parents. He is very good at creating handy acronyms, and uses PART to refer to these concepts. His work is amazing and I highly recommend it (see this link: http://DrDanSiegel.com).
As PARTners or PARenTs, our relationships benefit from a daily dose of: a present moment together, with focused attention, to lovingly respond and enhance trust. That is a long sentence but the time it takes to read it, is about as much time as it takes to do it.
