My 8 week old I'm exclusively breastfeeding had yellow normal poos up until 4 days ago when they turned a little greeny, then fully green then back to yellow and green. I just noticed some foam in the nappy green. I'm worried about having no hindmilk? I pump one session a day for dh to give a bottle to baby. Noticed not as much 'gold top' fat as I was getting before. Weight gain is good as of Friday still gaining. Milk looks watery when I hand express. Has anyone had the same issue? Thankyou in advance
