I have been weaning DS2 off the boob for the last 2 and a half weeks and he is so much happier on the formula. He is not constipated or anything.

But......

His farts STINK!! They smell like he is on full on solids and has been only eating red meat for the past 2 weeks. They are so rotten......Is this because of the formula?? Is it normal for them to be so stinky when he is formula fed??
