If there's room, you could try sitting in his playpen with him. Just sit in there and read or use your laptop, and just ignore him, and see what he'll do. If he gets veggies, you could try hand feeding him his veggies, or if that's too much for him, just put his veggies in a bowl next to you, so he'll have to approsch you to get them. Don't try to touch or pet him yet. You just want him to feel brave enough to approach you.
