Congrats on the babies, you'll know what true happiness is when they arrive.
I'm in the process of putting together a baby emergency kit. I'm using a sterilite tub from walmart. The first layer will be 2 of the thicker blankets then 3 recieving blankets. Then I plan to put 3 bags in and fill one with 1 pkg. disposable diapers, 1 doz cloth diapers, safety pins, plastic pants, diaper rash cream, some baby wipes, a few wash cloths and 4 changes of clothes. In another bag i'll put 2 cans of powdered formula, a few boxes of dry cereal and several jars of baby food. In the other bag i'll put things like bottles a bottle brush, extra nipples,small stainless steel bowl, medical supplies and anything else I can think of that may be needed. In a pinch, the tub can be used as a bassinet. Any other ideas?
