If you leave your child as your beneficiary, then yes for certain. Check with the HR Department of your employer to view your current beneficiaries and update them if necessary. You may also be able to do this online with your plan provider.
If you are currently married, the spouse will receive the proceeds, unless they have signed a spousal consent form giving up their entitled benefit.
I would like to encourage you to seek the advice of an attorney and accountant to make sure that your estate is directed to the beneficiaries of your intentions. They will encourage you to look at all beneficiary forms, such as life insurance and retirement accounts, and update provisions in your will.
