Sick at daycare

So my son’s been a little sick this week (cough and snotty). I kept him home on Tuesday because he obviously felt bad, and on Wednesday he was feeling better so he went to daycare without issue. Thursday he woke up and was a little clingy and I wasn’t 100% sure if it was sick again or a phase he’s going through, but he was fine after 15-20 mins running around the house and laughing, so I took him to daycare. Her policy is they can come if there’s no fever or puking. I told her to call me if he was acting sick again and needs to go home, I’m only 5 mins away and I’d come get him immediately. I didn’t hear from her so I assumed my baby was okay. My boyfriend picked him up later and apparently she was pretty mad at us for taking him to daycare today because he ended up not feeling well and was super clingy and didn’t let her tend to the other kids. He was a miserable sick baby when he got home too. I’m mad she didn’t call me and send him home early like I asked, but somehow I also feel like I did something wrong by taking him in the first place or not texting her for an update or not having spidey senses that my baby was sick 😞 Sometimes working and needing daycare suck.
