Fototechnischer Nachteil - die meisten Bilder sind verwackelt. LOL
Since Soren is able to crawl it is not so easy anymore to keep him on a blanket outside. But we have a HUGE playpen in the yard and we started using it. It is very comfy, spacy and safe. There's one disadvantage, your hair spikes in it. So forget styling.
Disadvantage regarding pictures - most of them are neither straight nor sharp. LOL
