Relieving engorgement/decision to not breastfeed baby

I’m 4 days post partum so my baby is 4 days old and my boobs have started to become really hard due to lactation starting. I’ve made the decision to bottle feed with formula due to me working full time in the military and baby girl will be attending daycare as soon as my maternity leave ends.

1. What can I do to relieve the pressure but avoid stimulating my breast and tricking my body into producing milk?

2. How long does breast engorgement last? And will my boobs ever go back to normal?

3. What are some signs to look for with breast engorgement that could indicate something is wrong & need medical attention?

If you can answer my questions, thank you!!
