How many times is too much poop for 6m baby?

Hiii mummies! FTM here. How many times does your baby poo in a day? Especially after the start of solids. My baby usually poop 2 times a day. But i realised after changing FM for 6months old & starting solids my baby poop 4 times a day everyday. I dont know if it’s normal or could it be diarrhoea?
