The answer is no. But the children born from this marriage will automatically become US citizens. The spouse of US citizen will be eligible to become US citizen after he/she (the non-US citizen) stay in US for a minimum of 3 years as a Permanent Resident.
As long as you pay taxes and still have "ties with US" as proof of your intention to return to US and to continue to be a US citizen, its not a problem if you stay outside US.
It makes no difference how long a US citizen of ANY age is out of the country. "Once a US Citizen, always a US Citizen." -UNLESS- you renounce your US citizenship and become a citizen of another country. However, since the question is about a 'minor' child that eventuality should not arise.
