I have a just turned 4 yo DS and I have to admit that I am absolutely rubbish at playing with him.
Are there any games you like to enjoy playing with your small children or do you just grin and bear another ‘let’s build a ramp for the cars’ game 
In all seriousness though, he is great at solo play and I love taking him out and about and talking to him about stuff etc but I do struggle to think of things to do when we are at home. Any suggestions please?
