We have some when C was about 3-4 months old. They set up a "seat" to prop her up, and E is sitting next to her. There's another one where he is laying down and we proped her up to be leaning over his back. And my absolute favorite is she's propped up in the seat and he's leaning in and kissing her forehead.
Sorry don't want to post pictures though, too many creepers that steal pics.
