unfortunately, she's in what i like to call her DIM phase or "do-it-myself" phase of her toddler-hood. which sometimes means that she likes to brush her own teeth without any of mom's or dad's help. we usually let her give it a try and wince when she gives her teeth a cursory brushing, and then sucks off all the fruit-punch flavored paste from the brush. then we go back in and do a proper cleaning.
of course, there will be a day when she'll brush her teeth without our help. but how to teach her the importance of doing a proper job? i found this idea (via ohdeedoh!):
how cute is that? i know my daughter will love pretending to brush these marshmallow teeth.
