Baby’s Poop 2.5month old (on formula)

Hello, is it normal for a baby to poop about 6 times a day? :( After her rotavirus vaccination, she had diarrhoea so went to the pd and changed to isomil. She was pooping 10 times a day during and after feed (few days after vaccination) It was okay for awhile so switched back to her Nan formula. Then she went back to pooping after her milk (not straight after but maybe 1-2hours after that kind) which is about 5-6 times in a day. Is this normal? Am currently putting her back on isomil for the time being again Ps. I wouldn’t say her poo is watery. Looks pretty normal actually. Just that she’s pooing a lot . #advicepls #firsttimemom
