I do lots of similar things with N - he also does play alone a bit with me in the room or in the kitchen or whatever - i dont think this is a bad thing???
when ia m cooking i give hima spoon and a bowl and he 'stirs' - or he sits in his highchair having a snack and i do a 'cooking show' for him - which he loves. i also havea cupboard with plastics in it which he unpacks while i am cooking...
N LOVES music - so we often have music on (kids music or my music) and we sing and dance. i have also taught him some songs which he now does actions too - twinkle twinkle, happy and you know it and he is learning incy wincy spider.. he bops along to any music.
not so into tv but sometimes i tape playsvhool and we watch it together and sing along to the songs
he loves the swings at the park - i go most days when i pick him up from daycare if it is sunny
also he still jusy loves chg in scene - playing with toys in diff rooms, or outside
and his latest things he loves to do - go all around the house turning lights on and off, openingand shutting doors - house doors and also all the cupboards, pretend phone conversations...
