If you are a widow for 4months with a adopted 4 year old looking to adopt what are my chances? My husband and I had plan to adopt again.

First, I am really sorry for your loss.

Widows or any single person can adopt. Single people do not have any longer wait period than any other family type. For information about single parent adoption and wait times see: http://www.adoptionhelp.org/single-parents

Having adopted previously will also not change your ability to adopt, and in fact families with children have a slightly shorter wait time than the average. See: http://www.adoptionhelp.org/open-adoption/statistics
