I was feeding my 6-month, A whole Single-grain Infant rice & I switched him to A wheat mulit-grain rice. I fed him only one bottle of this at around 3 in the morning & around 5, I woke up to him chokng on his own spit. For about 5-6 hours after that he continued to show a choking gesture & spit up this yellow fulid. I of course only fed him that one bottle b/c I thought maybe that's what caused it. But can switching the rice all of a sudden like that cause acid reflux?
