Roti ade tulang?

If afeef is a fussy eater, then fatini is totally opposite of that. her enthusiasm towards food is amazing! she can eat almost anything. the only problem is that, whatever she eats must not contains bones or seeds. so i must make sure that she has only seedless grapes, boneless fish, orange with the seeds removed and etc.. but problem is again how was i to know that 'roti pun ade tulang?'
i prepared a bread with egg for her in the morning, and she started eating the white part of the bread 1st until nothing is left except the 'kerak'. and she came to me with the 'kerak' in her hand "nah mama, tulang die..."
