Please help, freaking out a little

[LimeSlice]

Have you tried a different food? The same thing over and over can get boring.

Like Trish said, it could very well be teething.
Has he had a slight temp? Rosey cheeks? Or sticking his fingers in his mouth more than usual? A slight nappy rash?
Charlotte always went off food, back on the boob, sleep turned to crap, as do her poo lol and she was cranky on and off through out the day for no particular reason.
Especially with her first as she got her 2 front teeth at once.

STEP AWAY FROM GOOGLE!!! IT IS NOT YOUR FRIEND!!


Keep and eye on him, if he goes off then breast then think about it again. It is very normal to have greenish poo for soooo many reasons, you cannot use one ambiguous symptom to self-diagnosis

PS - lay him on his back and let him relax, somewhere warm, and gently but firmly use your fingertips to press his belly and lower abdomen. If it is hard or distended then he could be constipated or have some gas.
Get some baby oil or lotion and in a CLOCKWISE direction with a firm but gentle pressure, rub his tummy in a circular motion. Use smaller circles in clockwise direction and move around his belly in a large circle (hard to explain lol But if he had a clock drawn on his belly, you would move around the clock so a large circle, and do a small circle where every number be iykwim). Go quite low below the nappy line too.
You can also put his knees together and mover them together in a clockwise circle up to his chest/belly.

This will help manually stimulate his bowel motions and release any pockets of gas he may have. It will also help ease any clogs in his system.
