3.5 year old Separation Anxiety?

I'm hoping someone can offer some advice.

My 3 and a half year old dd (she has a 4.5 year old older brother) has been giving me a really hard time whenever I leave her. It makes no difference with who or where. I leave for 5 mins to move the car and leave her in house with DH and she screams.
I drop her at school, she screams and holds on to me, parents, sisters, dance, etc.
This has been going on about a month. I thought it had to do with going to school (this is her first year) but she didnt do it the first 3 weeks..

May I also add i'm 28 weeks pregnant with #3, but I'm not sure how that would add to it since baby is not here yet.

I feel terrible. Could use some advice please.

Thank you for your help and thank you for reading!

Going through exact same but my.son was just 3 in July. I have no.advice bc I'm in.the midst of it. He doesn't go to school hut it all started to happen when we started dropping my oldest, 4 off at school & he was crying.

My son was always ok with staying with my mil & now he screams bloody murder.

Yup going through this now with both my 2.5yr old and my almost 4yr old. They used to wave and push me out the door now it's a total struggle to even run to the car to get something, let alone actually leave. My youngest has been better with the school thing but the last couple weeks my oldest SCREAMS for me and clings on for dear life in school when dropping her off. Over the summer they LOVED staying at my MILs for a night once every week-2wks and looked so forward to it. Now they have to stay there next week and they are already crying about and telling me "please dont leave us mommy, stay with us!"

I am happy to hear I am not alone although I feel awful for us that we are going through this.

Maybe someone who has been through this can offer some advice.
