About to start daycare and I am freaking out!!

I am getting so nervous and anxious about taking my son to daycare for the first time. I am a first time mom and am just so scared to take him to daycare. I am just so scared that he won’t be treated well and that his cute personality will change. He starts in three weeks and the daycare has not sent me any like welcome information and what they are doing for covid so that is making me feel worse too. We signed him up in January because I did not realize there are waiting lists. The daycare has good reviews and I was referred to them by a neighbor whose kids went there. Ugh just so nervous. Anyone else gone through this too?
