Feel like a bad mom

My first kiddo is 9, I'm 38.3 weeks with baby #2. Yesterday hubs went out with our kiddo for a father/son day and went to a school thing. Our son and his friend wanted to set up a play date for today(the next day). My husband didn't set anything in stone, but kinda left it up to me. I can't drive far, and husband is on night shift so he's asleep today. So I told our son to talk to his friend and set something up for next weekend. I'll be 4 days from due but that's when my husband can do the driving. But I feel awful for not being able to do anything today. And if baby comes earlier than his play date I don't want him to cancel it. I'm sure my husband would still drive him though. But I can't help but feel bad for having to postpone it. 😞
