What does it mean when my 1 year old daughter don't breath when she cry?

Breath holding spell: It is not uncommon for children around age one to hold their breath for a few seconds after encountering a frustrating experience such as falling, etc. They will start to breath automatically within moments, albeit, it can be a scary experience.

Tantrum varient: You are describing a tantrum varient of childhood loosly called "breathholding spells".Rare but occasional in infants it peaks around 2 ; fades by school age in most.Often triggered by a scolding or your refusal to comply with their requests, they can turn blue, pass out ; twitch.It is not a seizure ; they self recover.Avoid locking eyes but monitor them.Don't reinforce the behavior by cuddeling.
