Your 21-month-old: Week 1

These days your toddler may be getting tired of sitting in a highchair, now that she can climb on and off chairs by herself. Think about buying a kid-size table and chair set, so she can feel like a grown-up at mealtimes (they're also great for art projects and snacks with friends). You may even catch her climbing out of her crib — a frightening moment for any parent. Don't be too quick to ditch the crib, though. Consider making it safer before you take on the challenge of moving your toddler to a bed.

對餐椅厭倦了嗎？好像有一點，不過大部分吃飯時候還是可以乖乖坐在上面，不過在阿公阿嬤家就不太願意坐highchair，常常都是溜到客廳沙發邊玩邊餵飯，調皮多了！！

Unsettling sleep habits
Being awakened by terrified screams is unsettling. Toddlers don't have nightmares as often as preschoolers and older kids do, but if yours has one, he's likely to be wide awake and have trouble getting back to sleep. Reassure him by rubbing his back or holding him. He may be agitated and frightened. Hand him a favorite blanket or stuffed animal for further comfort.

It can be tempting to bring an upset child back to your bed, but this could start a habit that's hard to break. Most kids will drift back to sleep with TLC and forget all about the nightmare by the next morning.

Night terrors are different from nightmares. During a night terror, your child's eyes may be open, and he'll move around, often thrashing, crying, and screaming. Night terrors are uncommon, but scary if your child has them. Typically you can't wake or easily soothe your child, which makes you feel helpless. And your child may appear to be awake, but he isn't.

Don't worry, though – night terrors aren't harmful. If comforting helps your little one during a night terror, it's fine to offer it. Don't force physical contact, however, or try to restrain your child. Stay close, stay calm, and make sure he doesn't hurt himself. He'll soon fall back to peaceful sleep.

Toddler preferences
Toddlers like things "just so." Along with tantrums and exploration, obstinacy is a hallmark of this toddler stage. Respect your child's preferences and interests, and let him make some choices, such as which jelly to spread on toast or which shirt to wear. Make it clear that some things – particularly behaviors that affect safety – are not up for negotiation.
