You have to keep trying. I introduced my 9 month old to solids at 5 months. It was a CHORE!!! He would spit back almost every little bit of what little went into his mouth. It took several weeks and lots of messes, but it's SOOO important to get them used to different tastes and textures before they are one, or you'll end up with a VERY picky eater. Although breast milk or formula still makes up the majority of the calories they need, 10 months is too old to be solely on breast milk. Try making your own baby food! That's a great way to save money, and adjust the taste to your baby's liking.
