Tummy time - as long as they want and are comfortable. Around this age you can start putting toys out and encouraging them to "crawl" to them - balls are especially fun because they only have to push them a little, we also had a blow up penguin that makes noise when you push it. I read that you should limit time in a jumper to 30 mins/twice a day, so that's pretty much what we followed. My 2nd son would have stayed in one all day if I had let him - my youngest son didn't like it at all. We also took lots of walks in his stroller with me pointing out things to him and talking about what we were seeing. My youngest started crawling at 7 months so after that he could get to what he wanted and started to entertain himself more rather than me having to do it for him. We also read a lot of books together at this age.
