My son started reception in September. He turned 4 on the 26th of August, so a young one. We did have the option to hold him back a year, but we thought he was ready. We ate now regretting this decision. He has had quite a lot of time off with illness. He seems to pick up every bug going. He is also struggling He is in the bottom of his class. The school said we could hold him back if needed. At first I felt like this would effect him emotionally, as he has made friends. The school said he has made friends with a boy that misbehaves and that is not helping him. We now are really considering holding him back a year. We have actually spoke to him about it. Which I wasn't going to do, but he seems happy to go back to nursery. Which is the class room next door. He knows the children in nursery. Then he would stay fresh in September. Im just not sure he this is definitely the right decision.
