We have a farm set with animals, veggies, etc, a castle with king & queen (actually this one, while appealing most ot mummy gets the least play out of all) and a school bus. Actually the bus is pretty cool cos it makes noises & says funny things - it gets played with quite a lot. A few of the matching people have been discarded (either chewed by dog or because donor child had them in her bath for a while - I couldn't get the mould out).

Snuggly, what age do you think the interest tapers off?
