Is this normal when solids are introduced

My daughter is four months old and she has had poop like this a little too many times if you ask me but I am hearing that it happens when solids are introduced but I also have never experienced this with my other two children she is formula fed and breast-fed She takes the yellow Can of Enfamil I have introduce solids to all of my kids at four months old I mean stage one baby food literally says to start at four months so peoples opinions on that is not what I am looking for
