Baby sleep at 18 months tends to be peaceful, but some children may want to continue playing after bedtime, ask for the company of parents or guardians, or even wake up during the night.

At 18 months, the baby already has teeth, which makes it easier to chew more solid foods in addition to being able to grip the spoon and cup well, being able to feed itself.However, at this stage the child tends to refuse some foods, and it is important to vary the preparation methods and repeat the offer of foods so that they get used to it.

In addition to stimulating the baby's sleep, it is important to avoid activities that stimulate the child close to bedtime, such as watching television, using the cell phone or leaving the light on, for example. if the child does not want to sleep, because he wants to continue playing or is more active, it is important to welcome and calm the child, trying to know what happens.

Baby feeding at 18 months

A baby aged 18 months can now eat the same meals as the family, having 6 meals a day, including 3 fresh fruit porridge divided between breakfast, morning and afternoon snacks, and 2 porridge "s alty", made with vegetables, cereals or tubers, legumes and proteins, for lunch and dinner, as explained below:

  • Breakfast: ½ serving of fresh fruit + breast milk, or 200 ml of whole cow's milk, or infant formula;
  • Morning snack: 1 serving of fruit + breast milk, or 200 ml of whole cow's milk, or infant formula;
  • Lunch and dinner: 1 tablespoon of cereal, such as rice or pasta, or root vegetables, such as yams and sweet potatoes + 2 tablespoons of vegetables, such as chayote, tomato and spinach + 2 tablespoons of legumes, such as black-eyed peas + 1 tablespoon of protein, such as meat, fish or egg;
  • Afternoon snack: ½ portion of fresh fruit + breast milk or 200 ml of whole cow's milk; or cereals, such as bread, oatmeal and corn couscous + breast milk or 200 ml of whole cow's milk; or roots and tubers, such as cassava, sweet potato and yam + breast milk or 200 ml of whole cow's milk;
  • Supper: breast milk or 200 ml of whole cow's milk, or infant formula.

Baby at 18 months still needs breast milk, which should be offered together with fruit porridge and on demand, which is when the baby wants to breastfeed.

For babies who are not breastfeeding, whole cow's milk is recommended as it is a drink rich in calcium, an important mineral for the formation of bones and teeth. But it should only be given in a total of 600 ml per day, as excess calcium can interfere with the absorption of iron from food.

However, in situations such as intolerances and allergies, for example, the consumption of cow's milk should be avoided. Therefore, before offering this type of milk to the baby, it is important to talk to the pediatrician.

Water intake per day

The Brazilian Society of Pediatrics recommends offering 1.3 liters of water a day to babies at 18 months. In these 1, 3 liters must be counted the amount of water present in breast milk, in cow's milk, the water used in preparations such as soups or stews and pure water.

It is important that pure water is always filtered or boiled, and should be given in a glass or cup, distributed throughout the day and between baby's meals.

Baby development

The 18-month-old baby likes to play with other children and usually walks alone, runs, can kick a ball, and goes up and down stairs without great difficulty. At this stage, the baby already has very good eyesight and points at what he wants.

Now the baby understands everything they say and can speak about 10 to 12 simple words, including “mommy”, “water” (water) and daddy. To help the baby speak other words, you can show an object and tell what it is called. For example, when you see a dog, point to the animal and say the name - “dog”, or even show other things in books and magazines such as “flower”, “tree” or “ball”.

At this stage, the child is very active and is always looking for games and, therefore, should not be left alone because he can open drawers to climb and reach the toy he wants, which can be dangerous.Likewise, it should not be left alone in the pool, bathtub or near a bucket of water.

As the baby already knows how to climb on sofas and chairs, it is also important that he stays away from windows, being interesting to put bars or protection screens to avoid accidents.

Baby toys and activities

Babies at 18 months like to play and discover their own body and the games promote joy, challenges to be overcome, in addition to helping to develop curiosity, confidence and creativity.

Some games to amuse and stimulate the baby's intellectual and motor development include imitation games, wheel games, imitating sounds and words, and puppet theater.

Simple nature play, such as picking up tree leaves from the ground, playing in the rain and mud, or playing with sticks, helps baby to be more creative, improve connection and respect for nature, as well as helping strengthening of the body's vision and defense systems.
