by | Sep 30, 2021 | Primary Care, Women's Services

As your baby continues to grow and develop, you may be surprised at just how fast they are progressing. Therefore, it is important for you to make sure that your baby’s development is on track. What should you expect during their ninth month of life? Take a look at a few important points below.

Weight and Size at 9 Months

By 9 months of age, your baby should be healthily progressing on their growth curve. The average baby girl is going to weigh at this age is approximately 18 pounds. Boys will generally weigh approximately 19 pounds at this age. Boys are usually slightly longer than girls, with both measuring between 27 and 29 inches at this age. Remember that it is okay if your child is not right in the middle of these measurements. As long as your child is tracking along their own growth curve as outlined by your pediatrician, there are no issues or concerns. If you have questions or concerns about your child’s weight or size, please do not hesitate to contact your pediatrician.

Development of the Senses

You are probably going to notice that your baby is going to develop quickly at this age. For example, many 9-month-old babies are already crawling everywhere. Your baby may be very experienced navigating your home, and you may even notice that your baby is able to pull themselves up to a standing using some objects. He or she may even try to walk around while holding onto furniture. This action is usually referred to as cruising.

Your baby is likely also going to explore their creative side as well at this stage. For example, your baby may like to hold a bunch of toys. You may even notice that your baby likes to throw them across the room. There’s also a chance that your baby may even say their first words at this age. Even though these may not be actual words, your baby is probably going to start the string letters together in an effort to communicate with you. It is important for you to interact with your baby regularly to encourage this type of development.

Feeding at 9 Months

By 9 months of age, your baby should be eating a very diet. For example, they should generally be eating between 1/4 cup and 1/2 cup of fruits, vegetables, and grains each. Your baby should also consume between 1/4 cup and 1/2 cup of dairy food every day. A few examples of common dairy foods include yogurt and cheese. If your baby still drinks formula and breast milk, that is okay! Your baby will probably be drinking between 24 and 30 oz of formula or breast milk every day.

Bathroom and Bowel Habits

Your baby should still be producing multiple dirty diapers during the day. You should expect that they are going to have a wet diaper after every meal or snack. Your baby should also have approximately one bowel movement every day. If your baby goes more than one day between bowel movements, that is okay; however, you need to make sure that your child is going to the bathroom regularly. If you notice that your child is straining to use the bathroom, then you may want to reach out to your pediatrician for help.

Coughing at 9 Months

From time to time, you may notice that your baby is coughing. Babies cough from time to time, so this should be expected; however, you do need to know when this is unusual. For example, you may notice that your baby turns to cough after they eats. This could be a sign of acid reflux. It is important for you to address this with your pediatrician, particularly if your baby is losing weight. If you notice that your baby develops a fever with a cough, then there is a chance that he or she may have a respiratory infection. This is another issue you may want to bring up with your pediatrician.

Sleep Schedule

SLEEP-SCHEDULE---baby-9-months

By 9 months of age, your baby is probably sleeping a total of 11 hours at night. A lot of babies begin to sleep through the night, which is probably good news for parents who are sleep-deprived by this point! A lot of babies also take two naps during the day. At this age, those naps should total between 3 and 4 hours. If you notice that your baby is starting to scale back their sleep during the day, this is a sign that they are developing.

Emotional Milestones at 9 Months

At this age, the part of the brain that is responsible for memory is starting to develop. Therefore, you may notice that your baby starts to recognize some familiar faces. As an example, your baby will probably recognize their parents or siblings. Your baby might also recognize sounds that are familiar to them. At the same time, this also means that your baby may start to develop anxiety when you leave the room. You should be ready for this as well.
Your baby will also probably become emotionally attached to certain objects. For example, this is typically the age where babies start to become attached to a security blanket. If you notice that your baby is having a hard time sleeping, this may be because they have been separated from that security object. It is important for you to keep this in mind as well.

Your baby is probably going to be chatty at this age. For example, your baby may develop speech patterns that sound more like words and sentences. It is important for you to respond to this with enthusiasm. That way, your baby tries to communicate more often. Your baby probably understands a lot more than you realize. Make sure you continue to interact with them.
