I have noticed that my 5 year old seems at times to have difficulty finding the right words, or being able to say what he'd like to without long-ish periods of delay. It's like that he has difficulty changing what is in his head into words. It isn't all the time, usually when he has something specific to say. When he is playing and thinking about it less he is fine and doesn't struggle at all.
Does anyone else have experience of this? Is it something that's quite common and will likely grow out of? Many thanks!
