Gift for Dad?

Looking for gift suggestions ! I really want to give my husband a gift for being so supportive during this pregnancy. We're expecting our 2nd girl, and he's really been a huge help with our 4yo and the household, especially during this third  trimester in addition to working and going to grad school full time. He surprised me with a "push present" for our first, so I want to surprise him this time. Nothing too expensive though, since our budget is tight. Anyone have any ideas?
