Switching formula

[marciblue1]

I want to switch from Enfamil to Kendamil Organic, b/c LO has been super gassy, lots of spit up and colicky. I’ve tried Enfamil Neruo, Gentlease, Similac and Similac sensitive and have had no luck. I was recommended Kendamil by a friend of mine, but I just switched him back to Enfamil Neruo b/c out of all the other ones I’ve tried that one was the least hard on LOs tummy.

Now my question is, should I wait another week before trying Kendamil or can I switch right away??
