Sorry to hear you didn't have a good first impression of the teachers. Of course you want a good teacher for your child, and you want to trust that they are being well cared for and educated when they leave your side. It is a privilege and a responsibility being a teacher, and hopefully, most teachers know this.
I remember my first year of lead teaching, I was very green to it, and didn't know a lot of things, either. I had one incident with a parent who yelled at me for not giving clear directions for parents to attend a school festival off-site, and I was in tears. But this parent apologize for being harsh, and we later became friends... so, I echo the sentiments of others to give the new teacher a chance.
Your daughter's teacher sounds a bit out of line, though. I would see how your daughter reacts to being at school, and make sure you have clear communication with her. Maybe see if you can sit in on the class one day. Mother's intuition is a great thing, and it is good to listen to it. At the same time, first impressions can be misleading, or you can change someone's attitude towards you when you yourself are kind. I had to do this with one of my son's previous teachers, who was rather mean. I tried to understand her point of view, and even asked her advice on some issues, and I gave her much respect as an older teacher, and she softened, and became much kinder to my son as well. We didn't stay at the school, but my son benefited from my compassion towards his teacher.
Definitely continue to identify your feelings about your children's education, both positive and negative, and be proactive about advocating for them. Education is vital to your children's future, so keep participating as you are. Best wishes.
