So expect your toddler to weigh around 18 to 20 pounds as they hit the one year mark. 

Your baby is also likely to grow by nine to 11 inches within a year. On average, a newborn is usually around 19.5 inches long. So by the end of the first year, they should be around 30 inches in length. The brain will grow up to 60% of its adult size within the first year.

Your baby will also be able to stand on two feet for up to five seconds by this time. If they lose balance, they will attempt to catch themselves. You will also notice that they will be able to throw a ball or at least push it forward by the time they are one year old.

At the age of one, your kid is all curious about new things and will be eager to learn. They will explore hundreds of different ways to use a torch. However, they are not going to stick around with something for too long. Once they get some other toys to play with, the older one will be thrown aside. 

To some extent, your toddler will begin to mimic you as you use different objects. They will also try to follow your body movement and gradually will master the skill of copying.

1. Communication Skills at 1-Year-Olds

Your baby should start using simple words by the time they turn one. Many toddlers start with the words “mama” and “dada” randomly before they turn one year old. Most of them will be able to address their mommy and daddy by using the right words. There are some other words they are likely to start using too.

For instance, if you say “put that down” they will give you some kind of reaction even if they don’t obey. This is a clear indication that your baby is being able to process the information that they are receiving through oral communication.

Pediatricians will advise you to feed them solid foods three times a day by this age. Your little one should also be able to eat by themselves. They should be able to hold round-shaped cereals and a sippy cup. When it comes to eating proper food, your one-year-old should be able to consume food items that contain honey. Her stomach will also gain the ability to process nut butter and eggs.

Things to Keep Out of the Menu

When serving, make sure that you are not giving your child anything that can be a choking hazard. For instance, avoid giving them pieces of popcorn, biscuits or a full grapefruit. Your one year old will be able to hold small objects by using their hands.

So keep an eye on them so that they don’t swallow any non-food substances like tiny toys, nuts etc. Your baby will also drink 22 to 32 ounces of breastmilk every day. In the 12th month, they should be able to drink whole cow’s milk. The quantity of milk intake should begin to slowly reduce by this time.

As your baby hits the one year mark, there are certain steps you should be taking:

Remove Breakable Objects

Your baby is now crawling or walking and will be eager to roam around the house. Make sure to keep unbreakable objects in the cabinets that your baby will be able to reach. Keep wooden spoons, plastic containers (ones that are certified as safe for babies) and whisks in the cabinets. You can also keep unbreakable objects of different sizes and shapes in a box for your baby to explore.

Baby-Proof your House

Make sure that your stairways are all gated. All cleaning solutions and pesticides should be kept up high in a place your baby cannot reach. The same is applicable for medications and sharp objects like kitchen knives, scissors and so on. 

Get rid of all the hanging cords that your toddler can reach out for and grab. Avoid having cords spreading all over the floor too. This will prevent your little toddler from stumbling on one of them. There are hide-a-cord accessories available that you can use for organizing the cords.

Make sure that you have door handles and door stoppers. This will protect your baby from getting hurt. If you have a fireplace in your home, use a fireplace grill to keep the toddler away from it when it is burning. Stow matches, logs and other items away from your baby.

Check with the Pediatrician

We have already described the standard milestones your baby is supposed to reach by the age of one. If your child is not progressing accordingly, talk with your pediatrician about it. 

However, as we mentioned before, not all babies progress the same way and at the same pace. Some are early while others take a little more time. So there is no need to worry. Just keep the pediatrician posted on your baby’s progress.
