Workshop on building up communication skill among toddlers

Few days back I was invited to take a workshop on building up communication skill among toddlers. Nowadays it is often seen that the toddlers are having difficulties in doing proper communication (verbal and non-verbal) as because from infant they are getting habituated to one way communication. They are very much addicted to T.V and smartphones. Also they are mostly staying in nuclear families, and hence most of the time there is none to talk to them with proper eye contact. As a consequence their communication skill is not building up properly.
The workshop went for a couple of hours and lots of parenting techniques were discussed to handle this crisis.
