Newborn (0-1 Month):

• •Per feeding: 1-3 oz
• •Frequency: Every 2-3 hours
• •Daily total: 16-24 oz
• •Feedings per day: 8-12

1-2 Months:

• •Per feeding: 3-4 oz
• •Frequency: Every 3-4 hours
• •Daily total: 22-28 oz
• •Feedings per day: 6-8

2-4 Months:

• •Per feeding: 4-6 oz
• •Frequency: Every 3-4 hours
• •Daily total: 24-32 oz
• •Feedings per day: 5-7

4-6 Months:

• •Per feeding: 6-8 oz
• •Frequency: Every 4-5 hours
• •Daily total: 28-36 oz
• •Feedings per day: 4-6

6-12 Months (with solids):

• •Per feeding: 6-8 oz
• •Frequency: 3-5 times daily
• •Daily total: 24-32 oz
• •Solids becoming more important
• •Formula decreases as solids increase

After 12 Months:

• •Transition to whole milk (not formula usually)
• •16-20 oz dairy per day
• •Food is primary nutrition source

The 2.5 oz per Pound Rule:

Most babies need about 2.5 oz of formula per pound of body weight per day.

Examples:

8 lb baby:

• •8 lbs × 2.5 oz = 20 oz per day
• •If eating 8 times: 2.5 oz per feeding
• •If eating 6 times: 3-4 oz per feeding

10 lb baby:

• •10 lbs × 2.5 oz = 25 oz per day
• •If eating 7 times: 3-4 oz per feeding
• •If eating 6 times: 4-5 oz per feeding

15 lb baby:

• •15 lbs × 2.5 oz = 37.5 oz per day
• •If eating 5 times: 7-8 oz per feeding
• •If eating 4 times: 9-10 oz per feeding

20 lb baby (6+ months with solids):

• •20 lbs × 2.5 oz = 50 oz would be too much
• •Cap at 32 oz per day once solids introduced
• •Remaining calories come from solid food

Important Notes:
