Breastfeeding ???

Hi ladies. Did anyone start off breastfeeding initially then move on to formula? Did you pump exclusively or have the baby latch on every time ?

I ask because I really want to breastfeed my baby girl (due in February) but lately I’ve started to have different thoughts towards it. I live a really busy lifestyle and formula is more convenient seems like. I don’t want to sound like a bad mother for saying that. I don’t know. What did you do ?
