I'm shocked and appalled!!!!!! My pristine highchair covered in regurgitated Trixie ammunition. . . Seriously, that highchair has seen worse. Much, much worse. I don't think you're ready to know how much worse until Trixie is done using it and then I'll tell you something that will make you feel like Mr. Clean. I told you this fancy highchair is annoying - I guess it's high price tag assumes you have a maid to clean it every day. I used to unscrew that whole belt apparatus and soak it in bleach water every year or so. You're in good shape so far.

Trixie hardly looks emaciated; quite the contrary. Don't worry about her missing a meal. When she is hungry she will eat. And also don't try to feed of her too soon after a bottle. Wait till her little tummy empties. Try showing her the food. If she rejects it take it away and try an hour later. It worked on my kids, including Jennifer's mother.

Good luck,

Marvin
