Honestly, when SHTF I believe the last thing law enforcement is worried about is stopping someone from trading liquor and tobacco items to survive. They will be kept busy enough with looters and killings im sure.
individually wrapped cigars
packs of cigarets or packs of 4 vacuum packed for smaller trades...
sm liquor bottles.. (we dont drink but Im putting 1 blackberry brandy in each of our bug out bags for help in the colder months)
small hygiene packs,
first aid packs,
Pain relievers or over the counter meds needed for different ailments.
I agree with the infant items.. I have a 6 month old, so stuff like that is on my mind as well...
infant Mre's...= formula stick packs, pedialyte stick packs, water, infant cereal, etc.. maybe a few cloth diapers and safety pins, small pack of wipes and a small pack of detergent so they can clean the diapers, and soap to wash the baby.
Not sure about putting disposables in there.. Not all babies are the same size.. cloth diapers can be folded etc... and disposables only last so long.. at least they can wash the cloth ones and reuse them..
My son is breast fed, but Ill still carry the formula sticks and a few bottles.... they also have those disposable bottles you can add to the pack .. but in my honest opinion, if someone with an infant doesnt have a bottle with them... thats just flat out stupid.. (unless they breast feed and something happens where they cant.. then I can understand a little... but still ..)
I wont be packing chocolate products.. saw someone do the liquor filled chocolates.. I think it depends on the time of year.. if your bugging out .. and its hot, that stuff is going to be a big mess and a waste of space in your bob if it melts.
remember that its best to cater to peoples vices.. when someone is addicted to something and there is no way for them to get it, they will trade.. course then again, you have to be careful that they are not crazy enough to do anything to get at your stock .. catch 22 there..

glad i got my husband to stop drinking and smoking..LOL
fact is...although i will work on having things like this on hand...id like to make sure first and for most that whatever situation arises... i am fully prepared to keep my kids and husband safe, fed , clean, and healthy and not relying on others to have things I might need down the road. my slight ocd will make sure of it..lol
