Any other moms sending little ones to pre-k this year?

I just registered my youngest for pre-k for the next school year and she got accepted. We went for her testing and she did wonderful! After we left I could not help but just cry. I’m having such anxiety about her going. She’s been home with me since she was born and never really been away from me that much. Pre k here is all day 8:10-2:45, Monday-Friday. I want to be happy she’s starting and she seems excited but I can’t help but be so upset everything I think about it. I’m also pregnant which is making me super hormonal 😭. I just keep thinking what if she’s scared when I drop her off, and what if she misses me and wants to leave. Ugh. My heart 💔.
