My newborn is 15 days old. The hospital used to give Nestle Nanexcella pro formula milk to my newborn when he was born. Can I switch to a different brand formula? And which formula milk is better or less colic producing?

A. Yes, you can mix different baby formulas, as long as one hasn't been recalled and you're preparing it safely in terms of the ratio of formula to water. If you're worried about mixing correctly, try preparing both formulas separately, and then mixing them together after they've been prepared
