Hey, don't feel dumb! So many times the moment passed for me. It may come in handy later. For the record I think Newmama's edit is the way to go. As for the last interraction there, it was ok, wasn't it? When it comes to seeing the baby, I think it's fine to put aside the visitation schedule (in your head) and say OK to him coming over and seeing the baby if you feel OK about it. It's a good thing for their relationship (bub and dad). Just don't do it at your expense or if it's going to detract you from doing your job as the primary caregiver, I reckon. Anyway, you did a good job of keeping busy as you say, and vague responses to his questions seem appropriate to me.
Maybe think about where you want to be with WH in say, a months time, and aim for that. Hope that helps...
