3 month old nursed 10 times yesterday

DS is about to start daycare so I need to get ready for sending him with bottles. I guess the best estimate is to just pump one day and feed him bottles only so I know what he eats at home and send him with at least that much. I have a decent freezer stash but he isn't wild about frozen milk - I think I have borderline too much lipase (sp?) but he will drink it but he doesn't like it.  He will drink my fresh or even refrigerated milk fine though and takes a bottle well.

He weighs between 14 and 15 pounds and was 3 months on the 9th.  When I have given him a bottle before he has no issues polishing off 9 ounces in 2 hours.  He's a bit of a chunk! 

How much would you send with your child?  Thanks!  Oh and what size bottles and how many?
