When testing a different formula, how long should you keep little on on it before making a decision to switch or not to switch? In other words, should you try it for a couple of feedings, a day, a week? How long does it take for a formula to produce it's results in your LO?
Re: Testing formula
I guess it depends on why you are switching. We had to switch twice. The first time we went from similac advanced to enfamil gentlease. We saw a DRAMATIC difference within 24 hours with a full turn around in three days. However the results were short lived.
We switched again to Enfamil Nutramigen. This was a longer and more difficult transition. Took about three to four days to see improvements with full effect in seven days. Now things are great! Hope that helps
