I spent heaps of time on the ground with the kids, still do. Jovie seems to be able to play happier when I've spend 5 minutes down there with her showing her toys etc...

I put Jovie on a mat & in a rocker or swing early on... I also wore her in the HAB on those days when you couldn't put her down. Even now though, 9 months later, she always complains when I first put her on the ground... and then she settles after a minute and starts playing.
