Spend the first few moments JUST OBSERVING your child. Let he/she get in the groove of what he is doing. Create a calm atmosphere by playing soft music and eliminating outside distractions
IMITATE your child’s play. After observing your child, gently join them. If they are coloring a picture of a house using crayons, grab a paper and sit down and join him/her by coloring your own picture of a house. If they are playing with a toy train track, gently add your own train to the track and follow his/her cue.
This shows your child that you care and are interested in what he is playing and you want to be part of his playtime experience.
