How old is your baby??
My girl do the same starting when she was 1 ....
She especially likes to do it when the food is long and thin ( like noodle, long vegetable)..
i ignore it...
I know it takes a lot of patience to 餵 BB...
Me too... I 'm the kind with no patience...
try this....
stop giving anything to eat 3 hours before meal... see if he'll eat faster...
if not,give yourself 1/2 hour to 餵.. if he doesn't finish, don't 餵 anymore... let he go hungry for one meal... see if he'll eat better next meal.
