Breath-holding is really terrifying for parents. It is the nuclear option in the toddler's armoury. Though it looks bad she won't hurt herself, so try and ignore it... easier said than done!

About 20% of toddlers use the 'breath-holding tactic'. When thwarted, they hold their breath, turn blue in the face and lapse into momentary unconsciousness.

Blue in the face!
At that point, the body switches to automatic pilot and breathing resumes and the child regains consciousness. The sight of their child turning blue and refusing to breathe is terrifying for parents, though it is seldom harmful to the child.

Why does it happen?
Your toddler is angry that she's been thwarted and this is how she reacts. It's really no different from any other tantrum, except that it's more distressing for parents.

Breath-holding tantrums can happen several times a day but they cause no lasting problems. If you want to stop it, the treatment is the same as for other forms of tantrums. Don't give in; ignore it or if possible distract your toddler. Most children grow out of the habit by the time they go to school.
