Hi mummies, notice there is a need to do a baby feeding and pooing care log. How long is the duration to maintain the log?

I stop when my baby is about 8months old . When his milk / sleep / poop have a shedule . But if the care giver is not you , maid or your parents , is good to have a log so you know what is wrong when baby is crying for no reason . IFC do a list of what they feed ( in case of allergy) poop (to take note of they are having diarrhea) and sleep time . Hope this helps
