We bought the size of "0-6 months", our daughter is now 7 weeks, and her fits of sleeping very well. The neck and arm cutouts sit and provide enough space, as it should be. As they still fit within the next few weeks to be seen. The substance is, however, quite thin, therefore less suitable for the winter (as the product title it already says). For the price you get a well-made product, the zipper popped and buttons do not go on to heavy or light and. He has at least survived without any problem after the first time, the washing machine - a different experience in the future I will grudge here.
