School or work ?

My 3 yo kid doesn’t want to go to school after 3 weeks of not going to school due to illness. I was supposed to start working on Monday but because of this I have to turn down the job offer. He is ok to go for half day but not full day. He keeps saying he doesn’t like to go for too long. So my plan now is to let him go back to half day and when he is ready then go for full day again. What will u do if u were me ? Am I doing the right decision ? I am a sahm for 2 years and was excited to get back to work but because of this issue I can’t get back to work again. I’m so stressed and do not know what to do.
