My son is almost 4 months. For the past few weeks his poop has been a dull green & a bit frothy. He is definitely getting enough hind milk so that's not it. Which is why I'm so confused. He's also super constipation. He goes poop 4-8 times a day & It's liquidy but he strains so hard & It's like it hurts. He's not gasy either. I don't know what it could be?! He is ebf (except once a week @ grandma's & she insists on giving him formula even though I gave her tons of pumped milk) any ideas on what could be causing his bad poop?
