Hi,
My DS (20 mo) is absolutely obsessed with trains. We have lots of Thomas TTE trains/ tracks as Ds1 enjoyed playing with it and was given loads by friends/ family. He builds track and long trails of carriages, makes only train- related sounds, knows how to find clips of steam trains on the ipad ( if he gts his hands on it, or my phone), and will watch it endlessly. He doensn't play or is intested anything else. This has been going on for about a month. I'm not sure whether I should let him be or make the trains 'dissapear' for a few days. I'm worried that this obsession is detrimentral to everything else he should/could be doing. Any advice?
TIA
