Changing formula

[Lauren8642]

My daughter is 12 weeks old on Wednesday and we did a straight swap of her formula 4 days ago how long will it take for her old formula to get out of her system?

Not sure about that one sorry @Lauren8642.

If you’ve swapped to a DF formula there is usually an improvement after a couple of days and the dairy should be completely out of her system after 2 weeks.

Do you wabt to tell us a bit more about what’s happening with your LO and which formulas you’ve swapped from and to?
