my son loves celery, with ranch or pb. he really has to gnaw on it hard which helps his teething.
string cheese. pretzels and cheese cubes. grapes. carrots and ranch. apples with peanut butter. cut up cucumbers with vinaigrette dressing.
Edamame, Celery peanut butter, carrots and ranch, handful of nuts, Apple and peanut butter, cheese and fruit
lunchables are good too, the ham and cheese with crackers. I roll up deli meats into little rolls and he likes them (sometimes)
