Breastfeeding to Formula

I’m currently breast feeding my baby girl, she’s 5 weeks old. I would like to transition into formula by the time she is 12 weeks. I work full

Time and have a 3 year old (who was breastfed til he was 2) and I am just not willing to put in the time and effort. Unfortunately, I’m just mentally not able to do it this time around, its exhausting. Plus my body breaks out so bad while I’m breastfeeding, I have tried everything under the sun and nothing clears it. Once I stopped with my first baby, my skin looked amazing (I miss it 😰)

I gave her some formula 2 days ago and she did not like it 😩

What formula does/did your breastfed baby like? I know they say breastmilk is super yummy and sweet to the baby ☺️
