I have built the house alone with my children (1 and 2 1/2 years old!). You have not really helped, but the items are so big and strong that they could not interfere with me. Only attach the roof I was almost desperate, because two other hands would have been better. The house is super to my children! By now, 2 chairs in it and their play kitchen. If the weather is good, want to eat even in the house 2. Then I crawl with pure and Fütter the little ones. My daughter just that alone. It's more fun to go out there again.
