With a new baby and little sleep, the mind works sort a funny--it is amazing what you remember and what you forget, and when this happens.
Here is something that will work for you-take one of those plastic holders that is attached to a lanyarad that you put your name tag in at a conference and put it around your neck with a small pen or pencil, index cards, a calendar from a check register or other itty-bitty calendar, and wear this all the time. When you go to bed, if you ever get to do that, take it off and put it at your bedside with your watch, glasses (if you wear them), and torch (a.k.a flashlight, it lets you check the babe without turning on a lot of lights and waking yourself up, etc). You might also put in some essential phone numbers, written large enough to read without glasses. Just don't fall asleep with this on if you are holding the baby or sleeping with the baby. I also would keep the car and house keeps on a string around my neck, saved locking the kiddies in the car on a super hot day once. You make your way through the haze. This is a tough time and just because the baby is older does not mean it is easier...you will keep adapting to new schedules and demands for...18 years or so.
