- Waves bye-bye

- Understands no and pauses or stops briefly
- Puts something in a container, like a block in a cup

Feeding
From 12 months, you can offer whole cow’s milk as a drink, about 2 to 3 cups (16 to 24 oz) a day. If you are breastfeeding, you can continue as long as you both wish. The AAP advises moving off bottles by 18 months. Honey is safe from now on.
Your child can eat most family foods, cut into small pieces.
Sleep
Toddlers usually need 11 to 14 hours of sleep in 24 hours, including 1 or 2 naps. Keep the cot free of pillows and blankets. Many families wait until 12 months to introduce a small comforter.
Your checklist this month
- Book the 12-month check-up and vaccinations.
- Book a dental check-up if you have not already.
- Keep your child in a rear-facing car seat for as long as the seat allows.
