I'm guessing you also mean 13mo.
Honestly enjoy the time you only get them that young for a short time & the more you put pressure on independence in the way you want it, the more likely the child is to want your help more.
A good rule of thumb is "provide the opportunity" ie give a spoon & finger food, give her a chance to try & then help her. The most important thing to help children eat though is to eat with them, they learn the skills & the food variety from seeing you eat. Infact Modelling & patience of all behaviour is the best way to help a child with any skill.
