What should your baby be doing at 11 months

Motor development

You will be amazed to see your baby cruising around the room with support [4]. He might also show independence by taking a few steps without you holding his hand. Some may walk unsupported in the eleventh month [4, 6]. Trying to flex his body in different ways, your eleven-month-old might attempt to get on his toes or stand on one leg. As his cognitive and motor skills are simultaneously developing, he enjoys putting one toy inside the other or his favorite blocks into boxes and buckets [5]. Beginning to learn to climb, the little one will enjoy getting up on crib rails, window sills or anything accessible to him [4].

Communicative development

Their language skills seem to be more matured by now. Though their vocabulary might comprise of only a few meaningful words such as ‘mama’ and ‘dada’, they will babble non-stop, most of which is difficult to understand [5]. Parents should keep talking and reading to their children as much as they can [7].

Cognitive and behavioral development

As his cognitive skills advance a step further, his understanding of getting back hidden objects becomes more pronounced [8]. The pangs of separation anxiety that had developed for the past few months goes on to heighten by now [5]. He is more skilled at pointing and waving, being able to follow your commands to a certain extent.

Moreover, the little one also goes through the phase of emotional development, throwing a tantrum, when he is asked to give up his favorite plaything or on hearing the command “no” from you. Developing a sense of individuality, your baby has also learned to express his likes and dislikes [4] or approval and disapproval [9]. With his attention span improving, he may be able to focus on a game or a certain activity for longer than before [4].

Sensory development

Their vision is much advanced, working in unison with their hands, helping them to grasp objects using their forefinger and thumb [8]. Properly coordinated eye and leg movements make them experts in crawling and cruising around [10]. They can arrange toys by their size, color and shape [4].

Because of a sharpened hearing skill, babies hear sounds at varied range and intensity. While they are overjoyed to hear pots and pans banging against each other [5], unusual sounds continue to scare them.

What feeding schedule should an 11-month-old have

What should your 11-month-old be eating

Most babies can feed independently, with their fingers or even a spoon. Having cut their first tooth already, with more in waiting, teething symptoms will persist.

There are some choosy eaters, keeping the spoon off their mouth and fussing about a lot [4]. Come up with creative breakfast and lunch ideas to make their meal time exciting. Babies can be given oatmeal (made from unsweetened oats), pancakes or waffles prepared using a whole grain mix, eggs (boiled, fried or scrambled), yogurt, as well as mashed fruits and vegetables[4,11,12].

They will be experts in eating finger food so give them more of it to facilitate the method of baby led weaning (allowing him to feed on his own) that makes your kid more independent. However, consult your doctor while fixing the baby’s diet.

How much breast or formula milk should an 11-month-old be given

Give your baby 22 to 32 ounces of breast or formula milk in a span of twenty-four hours [13]. Avoid providing whole milk or cow’s milk till he reaches the age of one [14].

What is the sleep schedule of an 11-month-old

An eleven-month-old sleeps almost through the night for 10 to 12 hours with about two naps during the day [15]. Most will refuse to sleep in a cot or crib, crying for their mother’s company [16].
