Like Ryan's mum said, it could be related to teething/constipation, but it could also be a preference for finger foods. It's a developmental thing that a lot of toddlers go through...they suddenly want to be independent eaters and finger food is all they want for a couple of months. There are several threads on this board with finger food suggestions that you might want to take a look at. When Tyler went through that phase, we did lots of steamed veggie chunks and ripe cut up fruit. Sometimes it's easier to make up a big batch and freeze what you don't use. Try offering some healthy finger foods and see if that makes a difference. If all she's been eating is cookies and cheese, those are pretty constipating, so you might find that some fruits and veggies help things along.
