Congratulations to you and your wife!! From my experience I find spending time with my kids will always win out over cycling. That said I love that both of my kids cycled with me when they were young and still both of them love cycling.
My commute changed in April 2014 from a 10 mile commute one way to a 6.61 commute one way. I miss the time on the bike in the morning so I make up for it in the afternoon by riding longer home. I can do this cause my kids are now grown and married.
My suggestion is to commute when it is available just to get bike time and enjoy your daughter as much as possible.
