Switching to exclusively pumping

Ladies,

After almost 8 months of exclusively breastfeeding, I have bought the bottles my son likes and am just going to pump! I can't take the biting anymore 😔 I tried everything from pushing his nose to my breast to sternly saying no and stopping the session. Im over it. pumping mamas, Any tips, tricks and how your schedules work? I'm a stay at home mom and he eats about 4-5 times a day and 3 solids a day. How many ounces do you put in each bottle as well? When he was a newborn baby, I'd leave 4 oz for dad to give and he'd drink like 2 to 3 ozs of it. Im sure he is drinking more but I can't tell cuz he's only ever really been on my boob lol
