How can I help my four year old be talking well for school?
By 4 years of age, your child should be really motoring with their speech and language. You should be understanding them most of the time, and starting to hear more complex vocabulary and sentences.
What research shows is that kids with really strong language skills have had more exposure to story structures at the 4-5 year age range. This includes hearing stories through books, but also the type of stories we tell to each other about our day. Encouraging family members to talk about their day over dinner is a nice simple way of modelling these story structures to young children, and it gives them the opportunity to try them out themselves. Its also really important to make sure reading a variety of stories is part of your daily routine.
