Hi there! My son was born with down syndrome, and had low muscle tone, along with developmental delays. At about one month old we had him in physical therapy a couple times a week! They showed me what to do with him on a daily basis--which pretty much was taking his legs between diaper changes and riding a bike in the air. They said laughing was good for the muscle tone, arm exercises, me just moving him...I'm happy to say it worked and he has good muscle tone as a teenager today. In my state of Tennessee, Chattanooga area, we have a few schools for special needs children--one is Siskin, the other Orange Grove, and I've forgotten the other one...but I enrolled him at about four years of age to help with those developmental delays. These type schools have trained professionals who know what methods to use to teach these wonderful children, and can help you to know what to do at home to help your child. That finger food feeding helps with what they call "fine motor skills"; but because your child will not actually eat the food that she puts to her mouth, have you considered hand over hand help? In other words, you make her hold the spoon and your hand over hers, then pick up the food and put it to you mouth--try that, hon, and good luck! Look into your area to see what might be offered for your little girl in the way of school for developmentally delayed children!
