The first year of your baby’s life is arguably the hardest, between adapting to motherhood, tackling postpartum depression, getting the hang of breastfeeding and learning how to store breast milk, and getting used to your post-pregnancy body. But so much happens in that first year! At 11-months old, your baby is developing, learning, and growing quickly. So, what should you expect for 11-month-old babies' development? What are some of the weight and height milestones your 11-month-old baby should be hitting?
The average weight for an 11-month-old baby is 20.8 pounds for boys and 19.2 pounds for girls. Meanwhile, the average height registers in around 29.3 inches for boys and 28.7 inches for girls. It’s important to note, though, that all babies are different, and their birth weight may play a part in how much they weigh or measure around the 11-month mark.
On average, most babies put on about 1-3 ounces a week and gain about half an inch in height every month leading up to the 11th month. It's normal for your baby’s weight and measurements to slow once they become more mobile. If you have any concerns regarding your baby’s growth rate or weight, seek out the advice of your doctor or pediatrician. They know you and your situation best and will be able to give you accurate advice or recommendations, or conduct further testing if necessary.
At 11 months, movement tends to vary. It’s likely that your 11-month-old baby is cruising around, attempting to walk, or maybe even already walking — and as they become more mobile, they may begin to look more toddler-like, losing those chubby baby cheeks (known as Bichat’s fat pad or buccal fat pad) and layers. Muscle begins to replace fat as your little one develops the necessary motor skills and movements to get around.
An 11-month-old baby is also becoming more and more curious about the world around him or her. As exploration starts, your baby will become more adventurous and confident in his or her movements. This is where childproofing is necessary. At this age, babies will grab at drawers or slide over to dig through shelves. You’ll want to baby proof your home by eliminating hazards such as open outlets, sharp corners, and easy access to dangerous items, as well as keep a close eye on them so they don’t scoot out of your sight.
But let’s dive into the specifics regarding your baby’s movement development.
