Hi, Kell
Honestly, at 10-months, I'd not worry. Kids develop at their own rate. Even if there was a delay developmentally, it wouldn't necessarily signal autism. It may just be a delay in some abilities or senses. Kids that age are so unpredictable. I have a perfectlly normal son who didn't really talk until he was two, and he wasn't even understandable until around 4. One of my daughters had feeding issues, and is totally fine. I know that doesn't make your worries go away, but some kids just grow at their own pace. But, I do agree with the op's advice: mention your concerns to the pediatrician, and get their take. Follow your gut, you are mom, and if you're still concerned, a second opinion can't hurt.
Take care,
Lily
