Ready To Feed to start?

Hi! FTM here due in Nov and plan to EFF. I was wondering people’s thoughts on starting the baby with RTF formula for the first few months. I know it’s more expensive, but I feel like the convenience may be worth it for those first tough months?? Was thinking of using RTF til the baby is old enough not to need the water boiled and then switch to powder. I have no idea what I’m doing so please tell me if this is a stupid plan, but it seems to me like paying a little extra may be worth it to save time and energy. Thanks in advance for any advice!
