Here is how I came up with affirmations for my children:
Step 1-make a list of things you want your kids to improve on or just work on in general
Step 2-make a list of areas that are important to you and your family (family, friends, school, church, future, work, health, etc)
Step 3-Write definitive statements using terms like "I am" "I do" "I love" "I always"
Step 4- Avoid statements like "I can" "I will" "In the future" "When I grow up." Those can have the opposite effect (I will- someday? When is the future exactly? You see?)
Step 5- Know that they aren't set in stone and can change as needed
And here is what my 3 cute kiddos will be saying each morning:
I love my family
I love to help and obey
I am kind and share with my family and friends
I am smart and healthy
I love to sleep. It helps me be my best
I love to go to school to learn and work hard
I love to dress nice and have my hair done
I always talk politely
I love to read. Reading is fun
I choose friends who are kind and good
I can do anything
I always choose the right
I am a child of God
