Help Your Child Feel Worthwhile

"Worth while" means "worth" your "while", your time spent (as in "stay a while").
You can help your child feel worthwhile, worth your time.
It only takes spending time focused on the needs of your child.
Through meeting their basic physical and emotional needs, a positive attachment has formed between you. Its like an energetic umbilical cord through which all feeding occurs, including direct learning of who they are to you.
In your busy day, I ask you to simply set aside a few moments: find a quiet spot with few distractions; hold your child or take their hand lovingly; make eye contact. This lets them know you really are interested in them. You really are wanting to be with them. You really are spending time focused on them.
This focused attention is a lovely place in which you can share and learn more about each other. Give your child a chance to let you know what's on their minds. (I use a plural choice of words because I am addressing many parents, however this is meant to be a time for you and only one of your children at a time, if you happen to have several.) It may last only briefly, but the energetic interchange will stay with you both forever, as a building of greater positive awareness of each other.
This same idea can be a fruitful and positive dynamic in any relationship, especially parent /child. Try it.
