1. Reward them when they do something good.
This will motivate the child and help them realize that when they put effort into something they can achieve it and get something good out of it.
2. If your child does something very well simply tell them they are good at whatever it is that they are doing.
This will bring the child to a realization of "well they think I'm good at this so maybe I really am"
3. Be there for your child when they fail at something they tried hard at.
Let your child know that everyone fails sometimes even with 100% effort so they have the security to know that it is okay to fail sometimes if you go back and better yourself to fix that failure.
4. Teach your child to keep on trying even when things get hard because success is not easy.
If your child fails and then they learn to try over and over until they get it right their confidence will build up from the success that comes with trying and succeeding.
5. Make sure your child knows how much you love and support them.
Knowing that they are loved and have the support of the people they love will bring confidence to children because they have a support system to fall back on if they fail which is comforting for them.
6. Help your child create goals for themselves.
If a child has goals and then achieves those goals by themselves they will build self-confidence from achieving what they set to achieve.
7. Let them make decisions of their own.
If a child makes decisions for themselves they will feel like they are good enough to do other things as well. It will give them a feeling of adultness and help them realize they need to make decisions to better themselves.
8. If a child does something wrong let them know that the choice they made was wrong but do not make them feel like they are a bad kid for making the wrong decision.
If a child gets into trouble and they get told they are a bad kid their confidence will go down. If a child is told that their decision was wrong and that they can be better than that, they will gain confidence in themselves hearing that they can be better and fix the bad decision.
9. Help your child realize that nobody can be perfect.
If your child believes that they need to be perfect their confidence will go down each time they mess up in something. If your child believes that being the best you can be is the best thing to do then they will be the best they can be with confidence even when they mess up.
10. Do not let your child compare themselves with anyone.
If your child compares themselves with someone else they will lose confidence if they do not feel as good at something as the other person. Let them know that everyone is different and has different talents.
These are just a few tips you can use to build your child's confidence so they are ready to be the best version of themselves!
