Dear all Mom
When you make formula, instead of shaking to bottle to blend the formula, you use the spoon to steer the formula with hot (not boil) water. You should try to limit the bubbles or any foam that form inside the formula so you baby can avoid having gas in their belly. Bubbles will become gas when they get into baby's belly and gas cause pain (extremely painful for all babies). I hope you pass this message on to all Mom and if you know how to pass it to all the Formula company, please do so for them to change the instruction behind on the can as well.
Thank you for reading my message. I learn this experience with my own son.
why didnt you just use the pre-made liquid formula or at least get that for when the baby was at the babysitters house? you cant expect someone to be psychic to your baby's needs. Haley did perfectly fine with her formula shaken up, all babies are different. And do you really need to post this 10 times, come on thats a little excessive!
