Hi J.,
I am also a mom of two kids (four year daughter and 10 month old son) and work full-time - not in law enforcement though. :-) Here are some things you can do that helped me when I was having issues. They worked and I am still nursing. Foods/drinks that help with milk production - oatmeal and root beer (diet or regular). Supplements that help - fenugrek and blessed thistle. Things to stay away from - caffeine and, believe it or not, peppermint and sage. I was chewing peppermint gum without even thinking about it and it really did kill my milk production. There was a noticeable difference after I stopped.
Good luck!
S.
