Do many send kids to school at 5?           09/02/2018 11:51 - Ask Mother Hen (Locality: Dublin South) ----------------------------------- Hi, I have a little boy who will be 3 this month. i have recently started thinking about what age to send him to school. I was airing on the side of sending him in 2020 when he will be 5 1/2. Do most people send at 4/5 nowadays. what are the pros and cons? i know obviously that it depends on if you think they are ready etc. Is he more likely to be the oldest in the class? he´s quite tall so i don´t want him to stick out like a sore thumb.
