Too early to be concerned?

My son is almost 10 months old. He eats really well most of the time but lately I’ve had a hard time trying to get him to eat different things. Like I don’t just want to make him mac n cheese everyday. And I already have one picky eater child and I don’t want another one 😬 but am I just over reacting? Is it normal for him to be a little picky now? I’m hoping the more things I give him to try that he’ll naturally just eat them eventually. Plus we’re going to a resort in the Dominican Republic for 8 days and everything there is so fresh. So it’s kind of like he’ll have to eat or be hungry... he doesn’t drink very many bottles any more. Just looking for some advice or personal experience. Thank you!
