Washington state does not have a state income tax, so no worries in regard to preparing a return for WA. If you lived in any other state before moving to WA in 2022 then you may need to file a part-year return for that other state, though.
The child-related credits you should watch for on your 2022 return are the child tax credit, childcare credit and possibly the earned income credit--if you qualify.
When you enter your children's information in My Info you will need their Social Security numbers. Make sure you say they lived with you the whole year --- even the baby---, and that you say their SSN's are valid for employment.
If your children are in daycare so that you can work, you will need the tax ID or Social Security number of your childcare provider so that you can enter that to get the child and dependent care credit. Make sure the babysitter knows you will be claiming that credit, especially if the babysitter is working as an independent contractor.
