Natural remedies for tummy troubles?

My 7 month old son seems to be having some tummy troubles today, being a little fussier and clingier than normal, lots of tossing and turning during feeds and having very loose stools. He’s still peeing like normal and has no fever. Does anyone have natural remedy suggestions for tummy upsets? He is breast fed, no formula and is eating purées once or twice a day. We haven’t tried any new foods lately. Keeping him hydrated offering more water today and keeping an eye on wet diapers. Also monitoring temp to look out for fevers if it’s a sickness. Any natural tips are very appreciated!
