Breastfeeding help

Lorena • Momma to 3 beautiful babies!🤍🤍🤍
I was doing occasional breastfeeding at night only, pumping and feeding him throughout the day and also formula feeding and didn't do breastfeeding for 2 days, tried today and my son refused to take it😞 I'm so upset and angry at myself. What can i do so he can latch on again?😞
