3.5 year old doesn't want to go to nursery. New baby too.

Hello,I was wondering if anyone had any advice, my 3.5 year old son doesn't want to go to nursery anymore. He gets hysterical before he is due to go. Clinging and screaming crying to me.He wakes up in the night before nursery crying how he doesn't want to go. When he wakes up he will continuously say how he doesn't want to go to nursery.I believe it's due to big changes, we have just had another baby (3 weeks old) and he has moved to the preschool part of his nurseryI was wondering if there are any tips or suggestions to make this easier for him?He calms down when he is there but it takes about 10 minutes.I know this is very new for him still and in time it will probably sort it's self but I just want to make this easier for him in the meantime. Thanks!Just to note he has been going to this nursery since he was 1. via /r/Parenting https://ift.tt/3v801EM
