Baby Milestones By Month: Developmental Milestones 20 Month Old

Published Categorized as Baby Milestones By Month

What are the at 20 months?

We continue to discuss since my little one is now, hip hip hooray, 20 months old. We will therefore focus on the following at 20 months:

Weight and height


20 month old – Weight and height

By 20 months of age, a boy weighs about 25 pounds, while girls weigh around 24.4 pounds. Boys should be about 33.1 inches tall, while girls should be about 32.6 inches. Boys are taller and heavier than girls.

Speech in a 20 month old

The toddler should have at least fifty words in his or her vocabulary. Questions like “what” and “what’s that” will soon be added to the vocabulary, so be prepared to become an instant professor.

At this time, parents and caregivers should begin to teach the child the correct pronunciation of words and they should avoid baby talk. As we said in other posts, the development of speech can be enhanced by speaking with your child.

To further encourage speech, the parent can also ask simple questions while giving the child plenty of time to respond. Parents should also respond to the child when he or she attempts to speak in order to heighten that communication.

Having an elder brother is associated with slower language development

A research article on Science Daily (2019) revealed that Having an elder brother is associated with slower language development. Researchers followed over 1000 children from birth to five and a half years old in the mother-child cohort EDEN. EDEN is a mother-child cohort study investigating the prenatal and early postnatal determinants of child health and development (International Journal Of Epidemiology, 2015).

The children’s language skills were evaluated at two years, three years and five and a half years. Researchers tested their vocabulary, syntax and verbal reasoning and discovered that children with an elder brother had a two-month delay in language development compared with children with an elder sister.

The first interpretation that was made is that elder sisters are more willing to talk to their younger siblings than brothers and that elder sisters compete less than elder brothers for parental attention.

Walking in a 20 month old

Another normal developmental milestone at 20 months is that the child should be able to walk up and down stairs. However, this requires greater supervision and assistance by parents and caregivers. Children should always be accompanied when going up and down stairs.

Your child may be able to walk up while holding on to the rails. However, he or she may climb down while using hands and knees, or on the buttocks.

Most toddlers need to for 14 hours a day. This usually consists of around 11 hours at night and a two hour nap in the afternoon.

Parents and caregivers should try to establish a daily nap and routine. Both could be facilitated story telling and singing songs, which seem to sedate children. Comfort objects and toys such as a soft toy or blanket help children to fall asleep quickly.

As the child approaches two years old, he or she begins to assert greater independence over the environment. This may be expressed in bedtime poser struggles with the child sometimes refusing to sleep. Experts recommend allowing the child to have choices in order to satisfy that quest f or independence.

To achieve this, parents can allow the child to choose the bedtime story, the night wear, the toy or stuffed animal to take to bed. Allowing choices also help to strengthen the toddler’s self image and self respect.

At this time, parents may begin to realize that some toddlers resist going to bed. This could be evidenced by behaviors like rubbing the eyes, irritability, yawning or even appearing to be alert and wide awake. Refusal to sleep could be due to the child not wanting to miss any of the exciting activities in the home or could just be an indication of growing independence.

Like all other scenarios involving the child’s need for independence, parents should remain calm and keep a neutral tone. In other words, there is no need to raise the voice or to yell at the child since this is a normal part of the development.

The parent should remain firm and indicate that time is up when the child begs for more wake time. Sometimes a night light can be helpful, as well as prayer to assure the child that Angels are protecting him or her. The parent should also indicate to the child that he or she will return to check up on the sleep progress in five minutes and that you are nearby.

Another strategy is to teach the child to fall asleep alone and how to soothe him or herself to sleep. This is where the bedtime rituals are important since they establish a simple pattern that helps to keep the child stable.

Teething in 20 month old toddlers

Twenty month old toddlers may experience the eruption of the lower second molars. These are the teeth that are located at the back of the mouth.

Teething pain can be relieved in the following ways (Mayo Clinic, 2019):

– Soothing the pain with an over-the-counter remedy such as Acetaminophen (Tylenol, Panadol) if the baby is very cranky.

– Using a clean finger or moist pad to rub the gums and sooth discomfort.

– Using a water based cream moisturizer to keep the chin moist and drying the drool.

– Using a cold washcloth, spoon or chilled teething ring to keep the gums cool. Frozen teething rings are too cold and should not be used.

– Giving the baby hard foods to chew on. Examples include peeled and chilled cucumber or carrot. The child should be monitored closely to prevent choking in the event that pieces break off.
