Our space is limited, but I have been able to stockpile a few necessities for hurricaine season. Our baby is due end of Sept/early October, so I'm also trying to get the house ready for that. With combining coupons with sales, I've been able to stock up on a lot of toiletries, laundry detergent and cleanning supplies. I believe I have enough for at least 3 months and possible even 6months +. Food-wise, I've been slowly adding to my stockpile every time I go to the store. We're looking at getting a freezer next month and I'll probable fill that up with meats, breads, and frozen meals. I've also been slowly building up the new baby's diaper supply, and since DD is still not potty trained, I've been adding to her pile of pullups and wipes.
Right now I am working some so we can spend the extra money on supplies. When the baby arrives, we'll be depending completely on my husband's income since I won't get paid the 3 months + I'll be out.
oh, and I also tend to start my Xmas shopping in Jan, so I'm almost done with Xmas ( I even have my cards picked out). I do stockpile on presents for other occasions also.
