My son loves imaginative play too and playing with Lego. Making Lego models and following the instructions takes a great deal of concentration! If he can concentrate doing that, he can concentrate doing anything! Maybe it's just that he concentrates on things he likes doing - don't we all!!!
He loves the TV and focusses on this but I do limit it. He is not a sit down and draw/colour child. Outside he'll potter in the garden or he likes role play and imaginative play with transformers/Lego/buzz lightyear and so on.
My son has good concentration at the same age. This may be down to his personality - he's not particularly sporty so is quite happy to sit down and concentrate. However, we do try to limit access to TV and computer games and encourage him to play board games and do jigsaws.
Yes, it will come with age. How is his attention span with something he really loves - what are his obsessions? Is there a marked difference in how much attention he can pay to one thing versus another?
So, parents evening. I am told DS struggles to focus and concentrate for any length of time. Ask teacher if I can help, by lengthening his attention span. she says she has found nothing and that he is 'frustrating as he is capable'. Apparently he is bright and stuff is going in but he doesn't focus really at all. Will this come with age? Can I assist his concentration. Thanks
