Reality is hitting

I have exactly 2 weeks until my csection. 2 more weeks of just having my two little girls. In 2 weeks my son will be here too. How are they going to adjust? Will they resent me later? I feel my oldest already does somewhat at only 2! I’m so excited but at the same time I feel like these last 9 months have flown and I’m not ready. His room is prepared and we’ve tried to get his siblings ready but honestly you can only do so much to prepare a 1 and 2 year old. I’m just so scared things won’t go well and they won’t adjust. I never knew I could be so scared for a baby to be here! 😩😢
