Have the coat ordered for stroller tray when our daughter was 4 weeks old. I must say that the investment has paid off. She was nice and warm in the car. The tub is quite cold in itself due to the material, so that it was nice and warm from the back in the fur. Have unfortunately only until February (since she was 5 months old) can be used, as it was too big for the car. But we had been given a foot muff with lambskin for the buggy. I can also highly recommend.
