DGD is 2 ½ and loves imaginative games - we go on holiday on planes, go in lifts (corner of living room) and a taxi - driving is "Wind the bobbin up" song, swimming in her play tent, she loves the shopping game - Tesco granny, now Aldi, now Asda - that can last for over an hour. Her cousin is only 20 months but follows on as long as he has a car in his hand. DD2 used to play at vets with all her toy animals and DD1 at schools with her dollies (she is now a teacher!). Outside games gathering acorns for food and leaves to make a den. Orchard games are very good board games with lots for younger children - shopping, counting, cafes etc maybe more for 3 to 4 year old but toddler can get their own board but probably not actively play. DGS2 at 20 months is very active but short attention span - he loves moving cars about, jumping on beds! going for walks round our housing estate and seeing real cars, chasing the cat, kicking balls, toy trains. All of them including 6 year old love helping with housework!!! and baking/cooking. So really not things needing a great deal of thought to set up - just ordinary activities but child directed.
