12 Months
Welcome to the 12-month milestone!
Happy first birthday! Your baby is turning into a toddler, full of curiosity and determination. Around this age, many little ones are standing or taking their first steps, saying simple words, and showing more emotions and preferences. They’re eager to explore, play, and connect with others. It’s also a time of big transitions — from bottles to cups, and from baby food to family meals. Below, you’ll find helpful information and resources to support your child’s development, nutrition, sleep, and safety as they enter toddlerhood.
Activity Corner
Once your baby has reached 1 year old, you can introduce basic puzzles with large pieces to help develop their problem-solving skills and hand-eye coordination, while partaking in a fun bonding activity!
Tod-Tidbit
Children start by being ambidextrous! It is normal for your child to use both hands equally until they are about 2-years old.
Healthy Habits
At this age, you can transition your baby to homomilk (homogenized cow’s milk). This transition should be slow to allow your baby’s digestive system to adapt to the new proteins. Aim for less than 500-750ml daily to prevent iron deficiency.

Concerned About Your Child's Development?
You know your child best. If your baby is not meeting one or more developmental milestones, has lost skills they once had, or if you have any concerns about their development, don’t wait, trust your instincts and seek support.
​
Start by talking with your child’s healthcare provider. Share your concerns and ask about developmental screening. Early identification and support can make a big difference.
