Preparedness Mama had a nice list on some items to consider when making an Infant 72 hours kit. Since infants grow fast, you will have to remember to swap out diapers as the child grows. Infant 72 Hour Kit | Preparedness Mama Please note: many of these things will be items that you yourself can use. The diaper rash creme could be A&D ointment which is a multi-use ointment and should be in peoples kit. Sunscreen, get stuff suitable for the baby but it can be used for the whole family. Wipes are great to have in your pack so why not pack baby wipes and the whole family can use. The baby will not have its own bag, chances are high that the mom will incorporate the baby items into her bag/72 hour kit. As the baby ages make sure to add baby cereal because a hungry crying baby is not something you want in an emergency.
