Not sure if this is a health problem or not but thought I'd see if anyone has experienced a similar thing - my fourteen month old daughter has recently started holding her breath and blinking (quite slowly, but blinking hard) for a few seconds up to about 30 seconds. She isn't doing it during a tantrum, and its quite sporadic. She doesn't seem particularly concerned, but she doesn't smile afterward either (like, it doesn't seem like she's playing a game or doing it for attention).
Does this sound familiar to anyone? As I've explained it, it seems like nothing but I am pretty sure something is not right.
