IBS type symptoms

[Thingsthatgo]

My Ds who is nearly 6 has had IBS like symptoms for about a week. He isn’t unwell in himself, just mild cramps before using the loo. However he is pooing about 6 times a day, and it is ranging in colour from very light to very dark. When he needs to go it is pretty urgent and mostly not very solid.
Any ideas? I will take him to the gp if it continues, I’m hoping it’ll stop as quickly as it started.

I’d see the gp and if you have to wait a while I’d keep a diary of what has been eaten each day and what symptoms were each day to see if there are any patterns there.

Thank you. That’s a good idea, I’ll start a food diary.
