Once your baby is crawling, it does get harder to persuade them that sitting still for photos is a fun idea so there is definitely a lot of chasing and resetting once the initial surprise of an unfamiliar environment has worn off. That said, it’s a good work out for us and there are still tons of great photos to get.  If you’re interested in using a lot of props, then it’s best to get in while they can sit unsupported but before they crawl but a mobile baby isn’t an issue at all in the studio.
