FORMULA QUESTION

So my hubby bought similac advance on accident although I’ve had my daughter on similac pro advance since she left the hospital (she’s 2 weeks 6 days old) - I was told that it shouldn’t be an issue giving her the similac advance because the ingredients are similar. So the other night during a 3am feeding, I ran outta the pro advance and gave her the regular advance.

She hasn’t spit up, she finishes her bottles. We haven’t had any issues! However, I did notice since she’s been on it, she’s been pooping more often! Her poop is the same consistency as it was on the other formula. It’s just that with the other formula she was pooping like once a day and now it’s 2-3 times a day.

Should I be concerned?
