Not behind at all!!YEAH Children master utensils somewhere between the ages of 2 and 3. An open cup is between 3 and 4. Right now sippy cups are great. This is also individual as the above numbers are only the norm.
Letting her eat with her hands right now sends her so many messages. She is learning about texture and motor movements through touching things. She practices her fine motor skills through picking up small things with her thumb and forefinger. She practices gross motor movements as she uses her whole hand to pick up larger things and put them into her mouth. It is such a wonderful time to explore!!
She has so many years to learn how to eat in an acceptable way. Right now, I would let her play with her food
