这个了解的不多，你是想参加哪个军种，从事哪个方面的服务呢？要是去当小兵从头开始的话应该比较辛苦吧，但是如果能学门手艺（比如学个护士）可能会好一些。

网上看到的

You can pursue a nursing degree in the military through various programs such as the Army's Green to Gold program, the Navy Nurse Corps, or the Air Force Nurse Enlisted Commissioning Program. These programs allow individuals without prior nursing degrees to obtain their nursing education while serving in the military. Each branch of the military has its own specific requirements and programs for individuals interested in becoming a nurse through military service.

mm不知道是不是还有这方面考虑。如果没有更好的选择，这条路可以走的，小孩不是问题，只要新兵训练期间有人帮忙带就行。如果你对一些无聊但无伤大雅的规则容忍度较高，并且能接受被分配到需要的地方，就完全没问题。你的年龄目前空军和海军应该都可以，建议优先选空军。如果有其他问题可以私我。
