8 month old pooing 5 times a day!

Becky

My boy has always pooed about 3 times a day..that is just his normal but for the past week he has been going 5 times a day and last night he actually woke up and pooed in the night! Not sure what I'm doing wrong the only thing I can think is maybe he is having a bit more fruit in his diet (but bit that much more)The poop is mostly solid but last night had quite a lot of mucas..any suggestions?
