Valentines day at daycare

I’ll start off by saying. My son is only 17 months old and I know he won’t know the difference. But tomorrow we have to keep him home AGAIN from daycare, because he has a cold ( runny nose and a pretty bad cough). Now normally I would say oh well. He gets to stay home and spend the day with auntie (my sister). But tomorrow is valentines day and it seems like when any celebration at daycare happens (Halloween and Christmas) I’ve had to keep him home because he was sick. Next year he won’t be in daycare has I will be in may leave again. I just feel so guilty (and partly because of pregnancy hormones) that I could cry. I like I said I know he won’t know anything different. And I’ll have hubby drop off his gifts for the class. But I’m still sad. Not really sure why I posted on here. I think cause I said something from hubby and my mom and both shrugged and said he won’t remember anyways.
