You can also pick up some thermal blankets
My father-in-law wrote a book, a compilation of a lifetime (well, a lifetime depending on how long you've been alive) of newspaper columns about being a husband and father. You should buy it.
And if you do buy it via that link to Amazon, be sure to take advantage of the "related items" shopping list.
Amazon suggests you pick up a couple of essentials after buying his book, such as 50 feet of rope. Or maybe a first aid kit.
