Okay so I started my 6 month old son on solids 2 weeks ago, bananas and sweet potatoes. He did fine. I gave him pears this past wednesday, thursday and then again on saturday. Saturday evening he barely slept getting up every 2 hours, I nursed him as much as possible but nothing seemed to work. DH even gave him a bottle of ebm at 5 am b/c i was so tired. At 8 am I nursed him again, he started to spit up afterward and it was brownish. He spit up again it ws brown still with a little bit of blood in it. We took him to the ER...they checked his stool for blood but none, no fever, otherwise happy. They checked me for mastitis, but I dont have it. He did bite me the other day and I had a little cut, so they said he probably just swallowed some blood and was spitting it up. Came home everthing fine just using some lanisoh cream. Now his last 3 bm's have been dark green almost black and pretty thick ??? any ideas...he is otherwise happy. could this be a food allergy @ 6 months??
