How Much Do Babies Eat and Sleep?
Average Hours of Sleep
Newborn: 16-18 hours per day, distributed evenly over 6-7 sleep periods.
1 month: 3 naps totaling 6-7 hours and 8.5-10 hours at night (not uninterrupted)
3 months: 3 naps totaling 5-6 hours and 10-11 hours at night (not uninterrupted unless you're really lucky)
6 months: 2 naps totaling 3-4 hours and 10-11 hours at night
9 months: 2 naps totaling 2.5-4 hours and 11-12 hours at night
12 months: 1-2 naps totaling 2-3 hours and 11.5-12 hours at night
2 years: 1 nap of 1-2 hours and 11-12 hours at night
3 years: 1 nap of 1-1.5 hours and 11 hours at night
4 years: no naps and 11.5 hours at night
5 years: no naps and 11 hours at night
Clearly, this is an approximation and reality may be more or less, but it's nice to have some idea what is "normal" when you're navigating life with an infant. Kate was fairly close to this as an infant, I think. Now at 2.5, she only sleeps about 10 hours at night, but is generally still napping once a day for 1.5-3 hours (this napless weekend notwithstanding!)
Average Bottle Consumption (breastmilk or formula, I'll add!)
Newborn: 2-3 oz. every 2-3 hours, about 8-12 feedings per day
2 months: 2-4 oz. every 3-4 hours, about 6-8 feedings per day
3 months: 3-5 oz. every 4-5 hours, about 5-6 feedings per day
4 months: 4-6 oz. every 4-5 hours, about 5 feedings per day
5 months: 5-7 oz. every 4-6 hours, about 5 feedings per day
6 months: 6-8 oz. every 4-6 hours, about 5 feedings per day
Around six months, you've started solids, so liquid feedings might go down some. (Note that the AAP recommends not introducing solids before four months, including putting cereal in a bottle. They're linking early solids to childhood obesity, apparently.) I think Kate's eating was pretty much in line with this chart, though again, these are clearly approximations.
