Hi L.,
I am not sure why you are trying to control your daughter's eating. Don't you want her to learn to do things for herself? If you do everything for her all of her life, what will she do when she is an adult? Just relax and let her go for it. She will learn by practicing as we all do. She will eat what she needs it is clear that you are not trying to starve her. She will probably make a mess. I bought the zoo pals plastic utensils from the grocery store and my kids love them because of the animals. They want to always pick which ones they want. "I want the monkey spoon today." We want to raise independent kiddos so that we know they will be able to problem solve and think for themselves when they are older. If she purposely starts making a mess, remove her from the table immediately and have her have some bedroom time until she wants to come out and eat sweetly. But some spills are bound to happen, she's 17 months old.
They also make some really great bibs with big pockets at the bottom. I got some of the plastic ones with these pockets and they wiped off easily and the kids could pick the hotdogs or cheese and lunchmeat bits out of the pockets when they were done with what was on the plate.
Just relax, kids can be messy at times. And we have to be willing to give up control on the things we can no longer control with our children. They'll let you know when they are ready to start practicing. I am an extreme OCD sufferer and I have to mentally tell myself, it's only food, it can be cleaned up, and the long term goal is to let my kids think for themselves.
