Any mommas putting cereal in their baby’s bottles?

Are there any mommas putting a tad bit cereal in their baby’s bottles? I know it’s not recommended, but I’ve been messaging my baby’s doctor & they’re talking about recommending putting a tad bit of cereal in her bottle. She’s 11 weeks, so it kind of worries me, I wanted to get some other moms inputs. She does have some bad reflux, she spits up clear fluid, her eyes will water, she’ll choke on it, & she also just spits up often in general. We’ve switched formula a few times trying to correct the issue, but nothing’s worked. We went from similac, to gentlease, & now we’re on nutramigen (referred by her doc). Any thoughts and experiences would be greatly appreciated!
