Feeding Your 1- to 3-Month-Old
During your baby's first 3 months, breast milk or formula will provide all the nutrition needed.
As your infant grows, feeding will change. Babies move toward consuming more milk during each feeding, so they won't need to feed as often and will sleep longer at night.
During the next year — and, especially, in the first 3 months — growth spurts will increase your baby's appetite. Continue to feed on demand and increase the number of feedings as needed.
Your infant also will become more alert as the weeks go by, cooing and starting to develop a social smile. So there probably will be more interaction between you and your baby during feedings.
The following are general guidelines, and your baby may be hungrier more or less often than this. That's why it's important to pay attention to your baby's signals of being hungry or full. A baby who is getting enough might slow down, stop, or turn away from the breast or bottle.
Breastfeeding: How Much and How Often?
After the first few weeks following birth, breastfed babies start to feed less often and sleep for longer periods at night. You can be reassured that your breastfed infant probably is eating enough if he or she:
- seems alert, content, and active
- is steadily gaining weight, growing, and developing
- feeds six to eight times per day
- is wetting and soiling diapers on a regular basis
Your baby might not be eating enough if he or she doesn't appear satisfied, even after feeding, and cries constantly or is irritable. Call your baby's doctor if you notice any of these signs.
Remember that after about a month, breastfed babies tend to have fewer bowel movements than they did before. When your baby is around 2 months old, he or she may not have a bowel movement after each feeding, or even every day. If your infant still hasn't had a bowel movement after 3 days, call your doctor.
During periods of rapid growth, you may notice that your little one wants to feed more often. This frequent nursing prompts the mother's body to increase her milk supply, and in a couple of days, supply and demand will get into balance.
Exclusively breastfed infants should get vitamin D supplements within the first few days of life, but additional supplements, water, juice, and solid foods aren't usually necessary.
Formula Feeding: How Much and How Often?
Babies digest formula more slowly, so if you're bottle-feeding, your baby may have fewer feedings than a breastfed infant.
As your baby grows, he or she will be able to eat more and may go for longer stretches between feedings. You'll also notice that your baby is starting to sleep longer at night.
During the second month, infants may take about 4 or 5 ounces at each feeding. By the end of 3 months, your baby will probably need an additional ounce at each feeding.
One note about formula feeding: It's easier to overfeed when using formula because it takes less effort to drink from a bottle than from a breast. So make sure that the hole on the bottle's nipple is the right size. The liquid should drip slowly from the hole and not pour out. Also, resist the urge to finish feeding the bottle when your baby shows those signs of being full.
Never prop a bottle prop. Propping a bottle might cause choking and it increases the chances of getting ear infections and tooth decay.
A Word About Spitting Up
Many infants "spit up" small amounts after eating or during burping. Over time, this will happen less often, and be nearly gone by about 10 months. Spitting up a small amount — less than 1 ounce (30 ml) — shouldn't be a concern as long as it happens within an hour of feeding and doesn't bother your baby.
You can reduce spitting up in these early months by:
- feeding before your baby gets very hungry
- keeping your baby in a semi-upright position during the feeding and for an hour after
- burping your baby regularly
- avoiding overfeeding
- not jostling or playing vigorously with your baby right after a feeding
If your baby seems to be spitting up large amounts, is spitting up forcefully, is irritable during or after feedings, or seems to be losing weight or is not gaining weight as expected, call your doctor. And if your child has a fever or shows any signs of dehydration (such as not wetting diapers), call the doctor right away.
Contact your doctor if you have any questions or concerns about feeding your infant.
