i’ve been seeing orange spots in the enfamil gentlease. i’ve mixed and shook and let it sit for a minute or two and see them forming at the bottom of the bottle, when i touched it, it turned my finger orange. i haven’t noticed it but it’s been happening in every bottle for the past 2 days. and just this week his been spitting up after almost every feed, not wanting to burp and spitting up in his sleep. is the spots normal? i switched to similac because i was worried it was so kind of dye or something that shoukdnt be in formula.
