will he sleep in the stroller? if he won't sleep in the car seat and he has short A time, maybe you can at least get out for a walk or to a mall or something if you are getting cabin fever - you coudl do his catnap in the stroller or pick another nap that suits you and see if he sleeps in the stroller ok.
although the aim is for him to sleep in the cot/basinette most of the time, you do have flexibility. stroller/car seat sleeping is really only a problem when a baby NEEDS these things in order to get to sleep. in the early days when they are learning to sleep on their own it can be a bad thing for all their naps to be on the run, because they will become hard to put down at home, but as an every now and then thing it is fine IMO. Moms need to get out too and we can't all wait until baby is awake for 2hrs each time.
everything gets better/easier as time passes. you are getting used to him, he is getting used to the world, his eating shoudl get more efficient and easier as the weeks pass...
