I'm not being irrational right?

I'm 7 weeks pregnant, so it's hard to tell. My son attends the daycare that I work at. Today, dad was supposed to bring him in, because I had an appointment before work, and before I left I confirmed with dad that they'd be in around 9-10 Am. I go to work, do my thing and his teacher pops into my room to ask where he is. I dont know, dad has him. I sneak off to check my phone, and no message. K, no worries. Then another teachers asks an hour later. Then its lunch and the director wants to know if they are still expecting him. Still no messages, no missed call, nothing. I finally get off for lunch at 130, and call while I'm warming up my lunch. My husband has an asshole sense of humor and when I ask where my son is, he says "oh he's not with you?".

So the cook got to see me cry, which is fun. I was too upset to really talk, but told him he needed to communicate with me, and that I was scared. A lazy day at home is fine, not knowing where my son is is absolutely not fine. He texted me after saying that if I had checked our baby care app, I would see that he had a bottle and was down for a nap. He says he understands where I'm coming from. I told him that the app was not a replacement for talking to me, and that if he understood where I was coming from, hed apologize. He hasnt said anything since. Now I have to go back to work, and I just want to hold my son.
