movements. Some may poop every day; others may poop every few days. This is normal
as long as stools are soft. Let your doctor know if they become hard, dry, or difficult
Sleeping. At this age, babies
sleep about 12 to 16 hours a day, with two or three daytime naps. Most babies
have a stretch of sleep for 5 or 6 hours at night. Some infants, particularly those
who are breastfed, may wake more often.

Breast milk or formula is still all your baby needs.
If breastfeeding, continue to give vitamin D supplements. Breastfed
babies may need iron supplements until they get enough iron from the foods they eat.
Start with a small amount of iron-fortified single-grain cereal mixed with breast
milk or formula. You can also start with a puréed meat, another iron-rich food.
Use an infant spoon — do not put cereal in your baby's bottle.
If your baby is pushing a lot out with the tongue, he or she may not be ready
for solids yet. Wait a week or so before trying again.
Wait until your baby successfully eats cereal from the spoon before trying other
solids. Introduce one new food at a time and wait several days to a week to watch
for a possible allergic reaction before introducing another.
Pay attention to signs that your baby is hungry or full.
Do not give juice until after 12 months.
Do not prop bottles or put your baby to bed
with a bottle.

when awake. Create a safe play space for your child to explore.

feelings are intense, or you feel
sad, moody, or anxious, call your doctor.
Talk to your doctor if you're concerned about your living situation.
Do you have the things that you need to take care of your baby? Do you have enough
food, a safe place to live, and health
insurance? Your doctor can tell you about community resources or refer you to
a social worker.
Let your baby sleep in your room in a bassinet or crib next to the bed until your
baby's first birthday or for at least 6 months, when the risk of SIDS is highest.
Always place your baby to sleep on a firm mattress on his or her back in a crib or bassinet without
any crib bumpers, blankets, quilts, pillows, or plush toys.
Avoid overheating by keeping the room temperature comfortable.
Don't overbundle your baby.
Consider putting your baby to sleep sucking on a pacifier.
Don't use an infant walker. They're dangerous and
can cause serious injuries. Walkers also do not encourage walking and may actually

Keep small objects and harmful substances out of reach.
Always put your baby in a rear-facing car
seat in the back seat. Never leave your baby
alone in the car.
Avoid sun exposure
by keeping your baby covered and in the shade when possible. Sunscreens are not recommended
for infants younger than 6 months. However, you may use a small amount of sunscreen
on an infant younger than 6 months if shade and clothing don't offer enough protection.

vapor from e-cigarettes is also harmful.
