We got this activity house as a Christmas gift for our daughter. She was 12 months old then. It has now been 4 months since we've had it and I can assure you this is the number 1 thing our daughter uses when she gets up in the morning. This house is used multiple times a day. We follow the Montessori style parenting for the most part and this is not considered Montessori aligned, but I have no regrets buying it. It has so many activities on it ; she picked a few activities she was interested in and practiced those first. As she got older she explored more and more. There is one side of the house she still doesn't use so we hope to see her interest in that wake up some time in the future.Otherwise she has tried everything and is not tired of this house yet. The small lock could be better quality, but other than that no complaint
