Personally I would be keeping my eyes and ears open.
I have very little unconditional faith in schools and teachers after our experience of reception. We swapped schools and our child is now utterly thriving.
You get a lot of grief for questioning, and you get asked things like the head tilty "is this your first child", or people look at you like you're some sort of adversarial arsehole, but some schools do have shitty cultures, ineffective leadership, make poor choices for the wellbeing of all children. That was our experience of the first school, and it wasn't just us- lots of families have since jumped ship, 10% of the year group left for other local schools on the same day a couple of weeks back.
There's also the possibility that it was just a potential culture and personality clash between family and school.
I think retaining a healthy degree of suspicion and questioning is something that every parent ought to do with the people that come into contact with their child.
I trusted blindly in reception year and swallowed my concerns much to the detriment of my own child, and I bitterly regret it.
