Said by a girl in the middle of eating breakfast, the full dialogue is:
おひゃきにいたらいてまふ~
She appears to be sleepy and has a mouth full of food, so parts of the sentence are slurred. She is also a bit messy, as crumbs are strewn about.
I understand the latter half written properly would be いたらいてます, which I interpret as she is in the process of reaching particular state, and that state is indicated by whatever comes before the に particle. But I have no idea what おひゃき translates to or resembles.
Judging by the context I'm guessing it is related to being tidier or more attentive, but my Japanese vocabulary isn't extensive enough to know any similar sounding phrases.
