I have JUST been through this.
My LO now goes to nursery 2 days a week for 8 hours. She started last monday..
I started the settling in sessions 2 weeks before, and she cried every single time, for the whole time. I felt AWFUL. It didnt matter if I was in the room out the room she screamed so much. She was really distressed, like I'd never seen her cry before. Then after the first week of half hour a day, she started to be fine while I was in the room, but screamed when I left til when I came back. The 7th session I left the room and she only cried for 5 mins, and stayed in for half hour no tears, apart from when I came back haha. The 8th one, no tears at all, I left her there for half hour, only cried when I picked her up. And the 9th and 10th, nothing, no tears at all!
Now she started last monday and she has been BRILLIANT. Everyone in there was shocked as she was SO bad at the start, they thought i'd have to pospone going back and take another 2 week of settling in's because she was so bad but she completely turned around. I think its cuz I stayed in for the first 5 mins of each session and then quickly left. Now I just take her to nursery, hand her over and go. No tears! And when me/OH pick her up she is so excited! Giggling the whole time.
The settling in periods and the first day were absolute hell for me. Infact I posted a post identical to this, I was really stressed out and worried about it and everyone told me it would be fine after she got used to it, but I didnt believe it. And she did! Now I dont dread taking her there. Honestly it WILL get better. Plus she is just starting to go through separation anxiety which is a bad time for them anyway with new faces
Hang in there hun! Does get easier xxxx
