If you are breastfeeding or (in the future) pregnant, you yourself may qualify. Your 9 and 7 year old do not qualify due to age; 5 and up is not assisted by WIC. Your newborn may qualify if you meet the household income requirements.
You and your new baby may qualify for benefits! You can see here what food packages look like https://www.ok.gov/health/Family_Health/WIC/WIC_Approved_Foods/index.html
