My little one is 18 months and has been eating smooth peanut butter for a good few months now. I love peanut butter myself, craved it in pregnancy also. I like the crunchy one but now we share the smooth. Yep just give her some and just keep an eye out incease there is a reaction anyway. Aleesha loves peanut butter! she also dips breadsticks in it.
Also have you tried houmous, that goes down quite well with a breadstick.
