Ladies, can I get some suggestions on what bottles y'all are using that have a nice slow flow and are anti-colic? All of a sudden my LO is sucking down his formula so fast that he literally chokes himself and then spits up horribly. I pace his feeding and make him take breaks but it really doesn't help. Currently I'm using Avent bottles with the "anti-colic" twisted nipple, but I think the flow out of it is just way too fast for him. Thanks so much! ❤️
