I didn't use any cereals. I started with applesauce for about a week then switched to sweet potatoes the next. I waited until around six months though. But honestly he wasn't into baby food so I didn't push it. He eats a lot of what I eat now and he's 9 months. A lot of people would try to tell me to force baby food on him like no lol. Food isn't essential and he's BF so he gets all he needs from me 🙂
