Combo feeding advice

I want to start combo feeding more now than my baby is almost a month old (will start after shes 4 weeks in a few days). She’s a great nurser and I have a really good supply but I just need a little more flexibility since she’s eating so much now. We’ve been doing one bottle a day for about a week now but I am wondering if it’s going to be detrimental to do more than one a day some days. Does anyone have experience with this or advice? My husband does a 5am feeding since he gets up for work then but I’d like to incorporate one during the day too when I need to run errands or something so it wouldn’t be every day. I will definitely need to do more day time bottles when I go back to work but I’m just a little unsure where to start with this
