Thumb-sucking

[may12]

I know it's normal for babies to thumb-suck.
Pero paano mga sis kung grade 4 na yung bata, hindi niya pa rin naaalis yan?

My niece kasi is still thumb-sucking and we think she's too old na for that.
Yung kapatid niya kasi na boy, nung toddler eh nagta-thumb suck pero kusa ding nawala.
Is there something wrong with her? Is it related to her emotional health kaya or talagang may mga bata lang na mahirap maalis ang habit na to?

Naiisip din kasi namin na masisira ang teeth niya kaya worried kami.
