Shane started in the jumper when he was about 3.5 months. So when we first put him in, he used to sit and chill out for a while, then started swaying a little. These days, the moment he gets in, he looks around then starts bouncing around. He's got a lot more expressions as well, as compared to 2 months ago.
Thanks Uncle Gideon and Aunty Evelyne for the gift… it certainly has made mommy and daddy's life easier when we're alone with Shane. At least we get a smiling baby after half an hour doing our own stuff - just because he loves it, and does not get irritated after a while.
