Normal? Dr call?

My 14mo has pooped about 6 times today. Big and small poops and lose and regular firm poops. Right before bath he pooped and my husband said it was a little green so I checked and it was very very green like hunter green.

I’m not sure if this is something to worry about or could it be he’s got too much iron in his diet lately? The only change he’s had is adding culturelle probiotics into his diet and that was about 3 weeks ago.
