Growth and Development, Ages 1 to 12 Months - Common Concerns


Babies love to put objects into their mouths. To keep your baby from choking:

  • Be careful about the size of toys he or she plays with.
  • Watch out for everyday items that your baby could swallow, such as coins.
  • Be careful as you begin introducing solid foods to your baby between 4 and 6 months of age. Help prevent choking on food by not giving your child round, firm foods, such as hot dogs, unless you first completely chop them into very small pieces.

Diaper rash

Diaper rash occurs most often in babies who are 9 to 12 months old. Even though a diaper rash is uncomfortable, normally it isn't serious. Usually the rash clears up when you:

  • Change diapers more often.
  • Are careful about cleaning your baby's bottom.
  • Apply nonprescription ointments to the rash.

For more information, see the topic Diaper Rash.


Your baby is teething when his or her first teeth camera.gif break through the gums. Teething usually begins around 6 months of age. But it can start at any time between 3 months and 12 months of age. Your baby may show signs of discomfort from sore and sensitive gums, be cranky, drool, and have other mild symptoms for a few days before a tooth breaks through the gum.

For more information, see the topic Teething.

Sibling rivalry

It may take a few months before an older child shows signs of jealousy of a new baby. When your child realizes that the baby is there to stay, strong emotions and behavior problems may soon follow.

You can take steps to prepare for sibling rivalry. For example, you can:

  • Help your older child adjust by setting time aside for just the two of you.
  • Talk about how important it is for your older child to help care for the baby.
  • Give your older child a role in daily care, such as handing you a fresh diaper when you change your baby.

Separation anxiety

Beginning around 6 months of age, your baby begins to feel uneasy when you go away. This is called separation anxiety, or separation protest. You can help your baby manage these emotions by making sure your child is well-rested and well-fed before you leave. It may also help to distract your baby, such as with a favorite toy.
