Showing your child respect teaches them what respect is, as well as to in turn respect you as well.
There is a difference between fear and respect. You want your child to respect you - not obey out of fear.
Helping your child build confidence is easy! Believe in them, praise them for what they do right. Allow them to feel proud of their accomplishments. Tell them you love them.
Hugs, kisses, family time.... asking your child "what would YOU like to do?"
ask him/her for their help. allow him/her to try things that might be difficult, yet they can succeed at.
Remind them how special they are.
Don't put them down or shame them - alone or in front of people.
When they do get in trouble - talk to them in a positive way, rather than negative. Have him/her brainstorm what they could have done differently.
Make sure your child knows you love him/her - you just don't like the negative behavior.
Display good grades and art work on the fridge.
Brag about them to your friends and family in front of them!
Keep a 10 to 1 ratio: 10 positives for every 1 negative.
