Sending lo to childcare

To working mummies who works office hours and need to personally send and fetch your lo from childcare, may I know how you all do it? Assuming start work 8:30am and need 1 hour travelling time, lo need to reach childcare at 7:30am. After I end work at 6pm and rush to pick lo, lo will likely be the last one left in school? Seems like lo will be in school for almost 12 hours and I am feeling the guilt for sending him to childcare ☹️
