Breastfeeding while out

I want to take my baby out in his carrier for day trips but I am struggling to get the baby carrier off while holding him so I can breastfeed and also same to put the carrier back on afterwards.

I want to be able to take him out in it alone but this part is stressing me out to do alone as feel like I need to put him down to get the carrier on and off. Please do you have any tips? 😊
