Sucking Thumb?

I observed today and realised that many a times, Little Arielle was sucking her thumb. Best of all, she seems to be enjoying it leh.

Oh no, since when did she pick up this bad habit? Weaning her off her pacificer was not an easy job. Weaning off her thumb would be worst. Hopefully, this is only a transition period leh.

Or perhaps, she is teething??

Shall observe for another few more days then....
