Toddler development: 25–36 months

Emotional times

Two doesn’t have to be terrible

Between the ages of 2 and 3 years old, your toddler will develop important skills and show you more of their unique personality. A steady supply of nutrients throughout this stage will help to fuel their learning and provide the energy they need to stay active and alert. Learn which nutrients are important at this time and how to ensure they get enough, even when they’re going through a fussy phase.

Your toddler’s development: 24–36 months old

Your toddler’s development continues at a rapid pace between their second and third birthdays. They are learning about themselves and their relationships to others and the world around them, while becoming much more physically able and confident.

By the time your toddler is 2 years old, you’ll probably be able to tell whether they are right- or left-handed. Their preference will have been decided when they were in the womb, but it can take a while to spot, as children generally use both hands equally as babies. Left-handedness is relatively uncommon, with only 7–10% of the adult population being left-handed.

Whichever hand your toddler prefers, they’ll often use their dominant side to scribble, kick a ball and feed themselves. They may even be able to use their preferred hand to brush their teeth – with a little help.

Sometime between 2 and 3 years old, you may notice signs that your toddler is developing the skills and bladder control needed to use the potty. If they can tell you when they’ve got a wet or dirty nappy and start showing interest in the toilet, you may want to give it a try.

A healthy diet for your toddler’s ongoing development

Your toddler’s continual development between 24 and 36 months requires a steady supply of nutrients provided by breastmilk. Iron and vitamin D are two nutrients that are still vital for this stage.

Iron is a mineral that helps transport oxygen around the body and contributes to your toddler’s brain development. Found in high levels in meat, oily fish and eggs, it is also available from plant sources, including beans and dark green, leafy vegetables.

Astonishingly, about 30% of toddlers aged between 12 months and 2 years aren’t getting the recommended daily amount1, so every parent needs to be aware of this vital nutrient. Even if your child is being picky, try to encourage them to eat at least one iron-rich food every day. You can make iron-rich meats easy to eat by offering soft casseroles or stews or very thinly sliced meats. Vitamin C helps the body absorb iron, so serving vegetables with each meal, or fruit as a dessert will maximise their intake.2

If your toddler refuses to eat iron-rich foods despite your best efforts at encouragement, for non-breastfeed infants, an iron-enriched growing up milk can help to contribute to meet their needs.

Vitamin D is important for healthy bone development; it helps the body absorb calcium and phosphorus, which are vital for your 2-year-old’s growing bones. The body produces vitamin D in response to direct sunlight on the skin.2

Food sources of vitamin D include eggs, oily fish and fortified breakfast cereals. Including them in your child’s diet on a regular basis can help to increase their intake.2

For non-breastfeed infants, giving them a growing up milk is another good way to supplement their diet – some varieties are fortified with vitamin D as well as other important nutrients.

Encouraging healthy emotional development

Between 24 and 36 months, your toddler is at an important stage of emotional development. They are learning about feelings and becoming more empathetic to the feelings of others.

Sometimes, their emotions can run high, which can be scary for your toddler. They may occasionally experience more emotion than they can handle or communicate, and this can boil over into tantrums or even biting or kicking. This happens to most children at some point and the key is to stay calm. Overreactions can make children feel anxious, so try to avoid big outbursts: explaining your own emotions can be a good way to calm yourself and get some rational perspective on a situation.

You can help your toddler learn to cope by naming their emotions for them and letting them know it’s ok to feel anger, sadness or frustration. Being open about when you feel similar emotions can help them learn that everyone has feelings.

When your toddler’s development takes a step back

Toddlers can regress in their development from time to time. It may be a sign that they’re overwhelmed with the amount of development they’re going through or can be a reaction to a change, such as the arrival of a new sibling.

Normal toddler regressions include a talkative child reverting to pointing and crying all the time, a capable walker wanting to be carried everywhere, and a potty-trained toddler suddenly having more accidents. Don’t worry – regressions are temporary and with some extra attention and time, your toddler will be back on track.

The best way to respond to a regression is to acknowledge your child’s feelings. Ask questions to find out the cause of their worries or change in behaviour. Some one-to-one time is likely to provide the extra comfort your toddler needs to feel their usual self again.

Breastmilk is the ideal food for infants: it is best adapted to their specific needs. A healthy and balanced diet of the mother is important for the preparation and continuation of breastfeeding. Mixed breastfeeding can interfere with breastfeeding and reduce milk production. It’s hard to reverse the choice of not breastfeeding. If an infant formula is used for a non-breastfed baby, it is important to carefully observe the instructions for preparation and use and to follow the advice of the medical profession. Incorrect use could pose a risk to the child’s health. Socio-economic implications must be considered in the use of infant formula. After 6 months, in addition to breastmilk, water is the only essential drink. Do not hesitate to consult your health care professional if you need advice on feeding your baby.
