Bad habit or a cause for concern?

[kohym]

recently my wife and i noticed our 7m old baby girl making this sucking-her-throat kind of sound.

not sure if it is some habit she picked up or really her throat is uncomfy.

she also like to suck in and bite her lower lip.

any mommies here observed this before in your growing baby?

thanks.

my girl used to do it too, was a phrase she had for 2 weeks before moving over to do other stuff. i guess its that they found that they could do it (discover new things) and had fun doing it. after awhile they get bored and do other stuff

My son who is 10 mths still does it but for him its like he is thirsty and wants a drink.
