Why would you want to skip it and miss out on tax credits some of which might be refundable? Omission could actually delay a refund if you list any dependents on your return for any purpose. Nothing in the tax laws requires you to claim a qualifying dependent so if not claiming them doesn't affect your taxes, then you can file and not list them.
The 8812 is used to claim the child tax credit (generally nonrefundable), additional child tax credit (may be partially refundable), and credit for other dependents (nonrefundable). it you don't list dependents and you are entitled to the earned income credit; the amount may be limited.
