Updated in September 2019

A 5-month-old baby can already raise his arms so that you can take him from their crib or shows desire to go to someones lap, reacts when someone wants to take his toy, recognizes expressions of fear, displeasure and anger, and begins to demonstrate his feelings through facial expressions. In addition, he is able to raise his head and shoulders when lying down and to support himself with his hands, trying to drag, roll and play with the rattles or toys that are at hand.

At this stage it is very important to play and talk with the baby, it is very important to encourage and strengthen the presence of the father, so that the two begin to create a connection.

5 month old baby's sleep pattern

The baby's 5-month sleep lasts between 7 to 8 hours a night, without him waking up. One piece of advice that can be helpful is keeping the baby awake for longer during the day so that he can sleep better at night, creating a routine and putting the baby to bed at nine o'clock at night.

Your 5-Month-Old Baby’s Development

A 5-month-old is already beginning to perfect his language and uses the vowels A, E, U and the consonants D and B, vocalizing for himself or for his toys. At this point, there is a modification of the sounds that the baby emits and they may start laughing.

Some babies reject people they are not accustomed to seeing and begin to notice their own name, responding when they are called and becoming more of the environment around them.

At this stage, it is common for them to roll back and forth and lean on their hands, scream for company, babble to interrupt the conversation of others and draw attention to themselves. In addition, this is also the phase they start testing objects and take them to their mouth, some babies also like to put their feet in the mouth.

What are the best games for this age

An example of a game may be to cover a flashlight with a piece of colored plastic, putting it on and making it move on the wall while talking to the baby about the characteristics of the light, such as how beautiful, bright or funny it is. This game can help the baby establish important connections in the brain, activating vision and neurons related to the movements.

An alternative to a flashlight are colored cards made with cardboard or even painted with gouache paint, because the baby at this age has a special interest for colors that is an important part of the development of his intelligence.

What should a 5 Month old baby eat

At this stage, a baby's diet should be done exclusively with breast milk, preferably up to 6 months of age. When feeding the baby with milk powder, artificial breastfeeding can be maintained until 6 months, but water should be offered between feedings, especially in dry and hot days.

However, if the doctor recommends or deems it necessary, the baby can be given foods with a rich nutritional value such as egg yolk or bean broth, and there is also the possibility of introducing some foods such as cooked or raw crushed fruit, gluten-free potatoes or a simple vegetables soup. These options are especially important for babies who do not appreciate milk or who are not developing as expected. See some examples of recipes for babies between 4 to 6 months of age.
