does teacher to student ratio matter that much for CCs ? realise that most hdb cc max out the ratio which means each kid gets less attention :( will it affect their mental and emotional development?will they be less expressive as a result?

It matters to me a lot as I withdrew my kid from a preschool because the Teachers couldn't handle the kids.. especially when they reached 2 years -- 3 years old, it's their most active stage 😓diapers not changed when it's so full, accidents and bruises and Teachers not sure how and why it happened, toilet training and wet their pants but Teachers didn't notice until I fetch my child and she smelled of urine.. belongings put wrongly into other classmates' bags, etc etc.. all these happened more than 2-3 times.. I went for half day trial class at another sch (Pte school), the ratio is 1:12 for N1 too, there's about 9 kids at that time, we were there from 9am til their lunch, the teacher also seems to be unable to handle the kids well, didn't manage to teach much because the kids were all over the classroom, the teacher was trying to make the kids sit down on the mat and pay attention, and you know when one kid does something, the other kids will tend to follow.. ended up I only remembered she taught the kids "today is a sunny day, today is Tuesday" and then it's time for outdoor play... during lunch there's an Asst teacher, she helped to scoop the food and the main teacher distributed it to the kids, I saw one kid was having difficulty self feeding and he made a mess out of it, teacher only realised after I sounded it out to her that he's not very good in self feeding and 1/2 the noodles were on his uniform.. 😓. Of coz end of the day I didn't register my child with this sch.. fees range is $1300-$1400..not exactly cheap!
