Lucky guy who got a baby who respects schedules.

I admit it's really tempting: carry around a sleeping baby while doing some programming work. From my own experience, it IS possible, but one must be very flexible. I.e.: work whenever the baby lets you (you must be able to get focused very fast after interruptions); learn typing fast with one hand (in the other one you will hold the baby); find positions which the baby likes and which allow you to work, e.g. carry it standing in a scarf in front of you or on your back or -- what worked for me -- work with the laptop half lying on the couch while the baby is sleeping on your belly ;-)
