Our son is 3 years 3 months old. His weight is 12 kg. Is his weight okay or is underweight? I have started sending him to playschool. Should I shift him to nursery? Is his age the right age to start writing with a pencil? Should he be given to identify letters of more than one language at this stage? If I shift him to the nursery he will have to learn three languages and also will have to read letters and write them. Should he continue in the playgroup or he be shifted to the nursery classes?
