Poo after feed

Since june this year, my infant has been having this “diarrhoea” episode three times. I’m not sure if it’s exactly diarrhoea because the texture is still pasty but it’s just that she has been pooing frequently (about 1-2 hrs after every feed) and this episode will last abt a week. Anybody else facing this issue as well with their LO? It’s so tiring… Disclaimer: she’s in IFC since may this year.
