DS is 4 months on Friday and his last two poops had black specks in it. We thought two months ago eggs might be bothering (although at that time his poops were just mucusy and no black specks) him so i stopped eating eggs and his poops became normal. My diet is pretty plain and doens't change. The only things that happened this week were

1- i gave him frozen pumped milk from june when i was still eating eggs

2- i had some gatorade on friday

3 - i had some crappy fried food at a carnival on friday

the black speck poops were yesterday and today but he hadn't pooped since monday or tuesday of this week so these were the first poops with the older milk.

we are seeing his ped this week and will discuss it with him but would like to figure out what i might have done and how long whatever it is could be in his system.

thanks.
