Another nursery one. How many accidents is normal?

[TheCatsMeow]

DS is in nursery one day a week. I'm generally happy with them, they seem lovely and he always enjoys going. He is 8 months old and has just started crawling and he walks holding hands.

Now, DS is high needs. I'm under no delusions about that, he is into everything and very curious. But out of the last 5 weeks, he's been in the accident book 4 times.

The first time a child fell on him and scratched his neck. He had a big red mark.

The second time a child scratched his face. Again a big red mark.

The third time, this is the worst one. He had a black eye! Another child had hit him in the face with a toy, and then DS had scratched himself because he rubbed his eyes. It was swollen and looked very painful, poor DS was upset. I started to get suspicious here as this was the third time in three weeks, so I took pictures of it.

The fourth week nothing happened.

This week, I've found out another child has scratched DS on his eye!

AIBU to think they are clearly not supervising the babies properly?! I am really upset. But DS is my only baby and I am an only child, so is this normal kids stuff?

What would you do? I'm going to pick him up in a couple of hours and would like advice.

If you were left alone by the one person who was watching five babies then their ratios are out -I thought at that age it was 1:3?
