I've noticed it too. My daughter is 2.5 now. She'll go weeks where she seems to eat 2 crackers and a cup of milk a day. Then she'll have a couple days (usually no more than 2) where she eats and eats.
What can you do? Since she eats so few bites, make every bite count. Keep cookies and candies as special treats, not foods. Offer her a variety of healthy food during the day and let her decide to eat or not. If she does eat, at least you know she's eating something with some value.
If you buy cookies, get whole wheat fig newtons. If you buy goldfish, get the whole wheat ones. Does she want a snack? Room temp (or fridge temp) peas are tasty. Fresh fruits expensive? Canned fruits packed in fruit juice are a good substitute.
