In less than a year, your little one has more than doubled in weight, developed a number of new physical abilities, and is even learning how to speak and walk. It’s incredible to think how much your 11 month old baby has grown in such a short amount of time.

In this post, the baby experts at Mustela will tell you everything you need to know about caring for your 11 month old baby.

Caring For Your 11 Month Old Baby

With almost one full year of parenting experience under your belt, you’ve mastered several important tasks: carrying your baby, keeping your baby clean, and changing dirty diapers are all surely a breeze by now.

Despite your parenting proficiency, you might still have a few questions about your 11 month old baby. The baby experts at Mustela are here to give you all the information you need to take extra special care of your little bundle of joy.

Your 11 Month Old Baby’s Development

Let’s get started with your little one’s height and weight. On average, 11 month old boys are 28.7 inches (73 cm) to 29.9 inches (76 cm) in height and 19.2 pounds (8.7 kg) to 22.1 pounds (10.1 kg) in weight.

Girls at 11 months old are typically a bit smaller than boys, with an average weight of 17.6 pounds (8 kg) to 20.9 pounds (9.5 kg) and an average height of 27.9 inches (71 cm) to 29.3 inches (74.5 cm).

Of course, these figures are just averages. There is no evidence that a baby being smaller or larger than average is a sign of a developmental issue or medical condition.

Your 11 Month Old Baby’s Senses

All five of your little one’s senses — vision, hearing, taste, touch, and smell — have come a long way since delivery day. Let’s have a look at each of your 11 month old baby’s senses.


Your baby can now see clearly and sharply, even at long distances. Notice how their face lights up when you walk into a room! Your little one can distinguish between different shapes and colors and can identify specific objects, like a favorite toy or stuffed animal.


Your 11 month old baby has been able to recognize your voice and your partner’s for many months. Now, they’re able to recognize the voices of friends and family members, as well as other sounds. Keep speaking to your little one constantly. This will help their language skills to develop.


Since your child has been eating solid foods for roughly five months now, their sense of taste is developing rapidly. Continue letting your 11 month old baby try new foods, and monitor their reaction as they taste them. It’s normal for babies to naturally enjoy some foods more than others, so take note of which ones are your baby’s favorites.


Your little one is full of curiosity and eager to explore the world. This means touching every new surface and object they come across. Make sure to baby proof your home, and then feel free to let your 11 month old baby explore to their heart’s content.

Also, remember that your little one still loves to feel your touch, so give them plenty of TLC.


While your baby’s sense of smell is fully functioning, they cannot yet associate smells with specific objects. While they may enjoy the scent of, say, an orange, they don’t yet have the ability to recognize the scent as belonging to an orange independent of seeing the fruit itself.

Your 11 Month Old Baby’s Motor Skills

At this point, your 11 month old baby is:

  • Rolling over from their tummy to their back (and vice versa)
  • Lifting their body into a seated position during tummy time
  • Crawling around your home without difficulty
  • Sitting up on their own and staying in a seated position without support
  • Making fists and grabbing items firmly
  • Using their thumbs and index fingers to grasp small items (a pincer grasp)
  • Standing with support from adults or furniture

By 11 months old, many babies have developed each of these physical abilities, but it’s not a cause for concern if your little one hasn’t yet mastered one or more of them. Your baby will hit all of these milestones before you know it.

Your 11 Month Old Baby’s Feeding Schedule

Healthcare professionals recommend introducing solid foods to a baby’s diet at around six months of age. That means your baby has been eating solid foods for five whole months! By now, they’re consuming a wide variety of solid foods — fruit, veggies, bread, cereals, noodles, cheese, and beans, just to name a few.

Medical experts also recommend waiting until at least 12 months of age to wean your baby off of breastmilk and baby formula completely. For now, breastmilk and/or formula should still be a substantial part of your 11 month old baby’s diet, providing somewhere around one-third of your baby’s calories and nutrients.

Your 11 month old baby is still growing extremely quickly, so they need lots of food to nourish their body. In general, your little one should have three meals and two snacks of solid food per day, plus breastmilk or formula three to five times per day.

Your 11 Month Old Baby’s Sleeping Habits

Your 11 month old baby is likely sleeping soundly through the night, probably between 10 and 11 hours straight. In addition, your baby needs two naps every day, one in the morning and one in the afternoon.

Naps typically last 60 to 90 minutes, giving your baby another two to three hours of sleep per day. This adds up to a grand total of 13 or 14 hours of sleep every day.

Your 11 Month Old Baby’s Immunizations

There are no immunizations scheduled for the 11 month mark. However, your baby should already have received a number of vaccinations over the last several months. Here’s a list of those shots:

  • 1 round of Polio vaccine (IPV)
  • 2 rounds of Hepatitis B vaccination (HepB3)
  • 3 rounds of Pneumococcal conjugate vaccine (PCV)
  • 3 rounds of Diphtheria, tetanus, and acellular pertussis vaccine (DTaP)
  • 3 rounds of Rotavirus vaccine (RV)
  • 3 rounds of Haemophilus influenzae type B vaccine (HIB)

If your baby is behind on their shots, now is the perfect time to get them caught up. Talk to your doctor at your next baby checkup.

General Childcare Tips

At the 11 month mark, your baby is extremely mobile. That makes it more important than ever to follow baby safety tips and baby proof your home. Never leave your 11 month old baby unattended — even for a moment — and never leave sharp or dangerous objects lying around.

It’s also important to take extra special care of your baby’s delicate skin. Here are some of the skin conditions to keep an eye out for:

As these are all possibilities for your 11 month old baby, it’s crucial to use gentle, baby-friendly skin care products, like Mustela’s. We offer a variety of products made from natural ingredients, from bath time products, cleansers, and shampoos to hydrating lotions, baby oils, and sunscreens. All of Mustela’s products are made especially for your baby’s sensitive skin.

When To Be Concerned

Here are a few warning signs that your 11 month old baby may have a developmental disorder:

  • Your baby never smiles or laughs
  • Your baby doesn’t seem to make or hold eye contact with you
  • Your baby doesn’t seem to recognize your face or voice
  • Your baby is unable to crawl or support the weight of their own body
  • Your baby is unable to make a fist or grasp small objects

If your child is displaying any of these signs, head to the doctor’s office for an evaluation ASAP.

Ultimately, every child follows their own unique path of growth and development. Some babies hit milestones sooner than others. This is neither good nor bad; it’s just a fact of life. As long as your little one is getting plenty of hugs and kisses from Mom and Dad, they’ll grow up happy and healthy.
