Self feeding

Your baby is now 19mos you should purchase a few  toddler forks and spoons for her. When you give her  finger food also give her a fork (scramble eggs)  she will use her hands and get a chance to practice with her fork/spoon. You should also  purchase the small fisher price chair that you can put on the floor this is comfortable for your toddler to sit in .Just think about it when you are sitting at the dinner table are your feet dangling? It is  very important that you purchase furniture that is age appropriate for your infant/toddler.
 You are also teaching her self discipline ,the concept of sitting  this is a skill that is needed for school. She will let you know when she is finish and wants to get out the chair. You should read her cues.
 You are also teaching self-confidence by allowing her to feed herself and she is also  learning competence. All these skills are needed for school. Yes your baby goes to a baby sitter and to a daycare. You do not need a lot of time to allow your baby to practice these skills. Your baby needs repetition and consistency and patience. Remember that you only need to introduce the idea/concept one because the brain does not forget. The brain must be developed  as a whole.
