I have bought this for a friend's baby after my own daughter received it last Christmas, aged 1. My daughter loves it and still plays with it. It grows with the child as at first it is a fun set of teddies that they can pull out the carriages and put back in, and then as they get old it is great for practising colours and numbers. The teddies are a good size in that they also fit in my daughter's doll's house and are currently residing there. They can also be hidden around the house to make a teddy bear treasure hunt. The front carriage makes a 'choo choo' sound when pressed, much to my daughter's delight, but unfortunately this started to sound a bit odd (either because the batteries are running low or the connection got squashed) about 2 months after we got it - this is the only downside to the toy (and could be a one off).
Overall, I would highly recommend this product as it looks nice, is fun for babies and children to play with and can teach them about colours and numbers.
