My favorite parenting book is the Baby Whisperer. I bought it while I was still pregnate and read it cover to cover twice before she was born. I liked her ideas that babies like to know what is coming next. And when you have your child on a routine it is easier to figure out why they are crying.
This doesn't mean you have to follow this strictly, but if your baby is crying at 9:30 am, you know her next feeding is soon so she must be hungry. Of course I wouldn't let her cry until 10 because that's when the schedule says to eat. I'd feed her early when she asked. She soon got to know when food and naps were coming, and rarely cried. She was confident that her needs were going to be met, and didn't need to communicate them to me. Below is the schedule I used for the first 3 months.
Schedule: 0 - 3 Months
7am - Feeding. I'm not a morning person so I would do this feed in bed, and either put her back in her basenette or bring her into bed with me.
10am - Feeding. This is when I got up.
11:30 am - Nap. I picked times so she would be able to sleep an hour and a half before her next feeding. In the very beginning she did, but quickly cut down on how long she slept.
1pm - Feeding. Lunch for me.
2:30 pm - Second nap. I read a book or watched tv.
3pm - Feeding.
5:30 pm - Short nap. I didnt let her sleep past 6:30 or it would ruin her bedtime.
7 pm - Feeding. Dinner time.
8 pm - Bedtime. Our rutine was, pajamas, bottle, dinner (ours), then bed.
11pm - Dream feed. I pumped for this feed, otherwise she would fall asleep and not get enough milk to last the night. My bedtime.
2am, 5am - Night Feedings. By 3 months I was able to cut out the 2am feed.
Just because this worked well for me doesn't mean it will for you and your baby.
