How to get baby to eat a vegetable

I did this for my mini ! Steam, butter, salt and pepper

What about raw veggies? My little one loves snap peas, tomato, onions, snack peppers, etc.

I read something about how you can offer both fruits and veggies and just let them pick what they want because fruit has minerals and vitamins too. So just offer both and let them pick what to eat. Also, smoothies or veggie pouches. Hidden veggie sauces. Try new recipes. But remember the division of responsibility for eating - you decide what, when, and where you offer food and they get to decide whether they eat or not and how much they eat. Look at nutrition over a week long period, not a single day. Keep mealtime fun, family meals if possible. But try not to stress or make it a big deal, they're the best intuitive eaters at this age. Some days my son only eats fruit for breakfast, other days he's loving his eggs. Just keep offering and they'll eat what they want.
~disclaimer~ obviously there are sometimes eating challenges, ARFID, neurodivergence that makes eating difficult to navigate, etc. but most children have this stage. They'll get through it.
