Quoting Love Wedge +2:" What colour/consistency should his poop be right now? It varies from a medium yellow to green at any given time."
we are in the light yellow - to light green range. It will vary it all really depends on how much of what was eaten. I know now that if he falls asleep on the boob he is more likely to have a green poop later because he just had a short drink of foremilk. The more he falls asleep the more green poops he gets. When he was younger and doing this more often I would squeeze my boobs while he slept so he would continue drinking for about 5-10 minutes of hindmilk.
Now personally he will get thick yellow poops if I eat a lot of ice cream. Pizza and eggs seems to make him more gassy and have more mucousy poops. But yes other things can make them gassy besides dairy, like cabbage, broccoli, onions, ect. but not every baby is the same of course. The pickles may have done it for you though! Caffeine does affect your supply so be careful to drink lots of water on top of any caffeinated drinks.
As far as spit up, we always have a bit of spit up.. sometimes right after a feeding, sometimes not until 15 minutes or more later. It's normal and as long as it's not projectile and baby is gaining well then it's fine.
