try her now, as long as you stay with her just incase she should be fine, most babies that age are curious and everything goes into their mouths, they like the chance to do things themselves too, try her and if she doesnt take to it try again in a week or so, my daughter loves a piece of bread roll to chew on, toast fingers in the morning sometimes with dairylea or butter, other times with fruit spread, she loves cuecumber and melon slices- cool on gums,veg sticks cooked and raw she picks what she wants from a plate of nibbles, the mess is incredable but hey lol shes learning
my daughter is 6 and a half months old i was just wondereing when the best time is to introduce finger foods cos i am not sure
