3 month old holds mouth open? Pants and kicks legs and arms whem excited

[mongo123]

My baby is 3 mths old and holds her mouth open while panting and shaking her arms and kicking legs when she gets excited. She does this when she sees me or im holding her up and playi g with her. Her dad also and lately when she sees a toy like her overhead mobile and it happens only when she is excited. Does it several times a day in the situations mentioned. Can anyone say if this happened with their babies and if their kids turned out fine as they got older? My concern is that this similar behavious is often seen when kids have toc disorders or other neurological disorders so i guess i am just worried since i dont notice this with other babies. The panting yes. But the holding mouth open part....not really
..

Don't all babies do that? I think you'll find they do and much older than three months. It's quite cute actually.

She doesn't 'hold' her mouth open, her mouth is just open! That's normal when excited.

I do find it very cute too Maybe i could have worded it clearer but the holding mouth open is like almost like its locked up temporarily in the moment of excitement.

It must be really difficult to know what's normal if you're not seeing other people's babies!

But yes, as the PP said the vast majority of babies do this, completely normal.

So true...i have not been around many babies...None really since my siblings many years ago. But thank you...its a relief to know that most of do this too
