4 mo old green diarrea

M

My breastfed 4.5 mo old has a diarrea. Basically poops a small mount of watery green poop every hour or two. It has lasted for five days maybe. I am sure by now it is not a foremilk and hindmilk inbalance. He also has enough milk, because he has enough wet diapers. He is a bit fussy and eats for less amount of time and don't want to sleep as much as before, but that can be also a sleep regression. He doesn't seem to be in pain and he doesn't seem to be dehydrated.

And now the reason why I am asking. Doctors office is closed until new years (basically they open on wednesday next week) and whatever my son has, doesn't seem urgent enough to turn to emergency room in this flu season.

Does someone know what it can be? How can I help him have normal poops again? Can I myself eat something else to help?

(I eat the same foods as I did always so my diet has not changed, also he had an eye infection and med for it, but he has not gotten any eyedrops for three days already, so I kind of think that is not the case either).
